Chicago Colocation — Independent Guide to Data Centers, Providers, and Pricing in the Chicago Metro Market
The complete independent review of colocation across the Chicago metro market, with focused expertise on CME Group financial ecosystem connectivity, hyperscale campuses in Elk Grove Village, midwest enterprise infrastructure, and cross-provider comparison. For NYC metro market analysis, see our NYC Metro Data Centers guide. For provider comparison across all major operators, see our provider comparison guide.
Chicago sits at the center of the second-largest US data center ecosystem after Northern Virginia. The market divides across three distinct submarkets: downtown Chicago (350 East Cermak and the Loop), the O’Hare corridor (Elk Grove Village and Itasca hyperscale campuses), and the Aurora exchange corridor (CME Group latency-sensitive workloads). Every major provider maintains meaningful presence across at least one of these submarkets. Understanding which submarket fits your workload is the foundation of Chicago facility selection.

Consider this your independent Chicago colocation review.
Bottom Line: The best Chicago data center for most workloads is 350 East Cermak Road (the “Lakeside Technology Center”) in downtown Chicago, which combines the deepest carrier ecosystem in the midwest with direct access to CME Group financial infrastructure. Chicago colocation buyers face three distinct submarkets and multiple major providers: downtown Chicago is anchored by Digital Realty at 350 E Cermak with unmatched carrier density and Equinix CH1 with CME Group ecosystem access, the O’Hare corridor is dominated by QTS Realty Trust’s massive Elk Grove Village and Itasca campuses alongside Aligned Data Centers and Digital Realty facilities, and the Aurora corridor serves CME Group latency-sensitive trading workloads.
Among Sandler Partners providers, Equinix CH1 and CH2 anchor the financial services and payment network ecosystem, Digital Realty operates the flagship 350 E Cermak facility plus Elk Grove Village and Franklin Park campuses, DataBank Chicago serves compliance-heavy workloads with strong SOC 2 Type II and HIPAA BAA capability, CoreSite CH1 provides direct AWS, Azure, and GCP cloud on-ramps for hybrid architectures, and TierPoint anchors the mid-market and disaster recovery segment with cost-optimized value pricing. For mid-market Chicago companies (25-500 employees) evaluating cloud repatriation, high density colocation, disaster recovery colocation, financial services infrastructure, and hybrid cloud colocation deployments, Chicago delivers meaningful advantages over cloud alternatives at 30-60 percent cost reduction for stable workloads. Metro Colo Advisory evaluates the Chicago colocation decision for you at no cost.
Why Chicago Is a Different Market from NYC
The infrastructure decisions Chicago companies face differ meaningfully from NYC decisions. Understanding these differences is the starting point for any facility evaluation.
CME Group anchors the financial ecosystem
The Chicago Mercantile Exchange (CME Group) is the world’s largest derivatives exchange, hosting futures and options trading across interest rates, equity indexes, foreign exchange, energy, agricultural commodities, and metals. CME’s matching engine sits at their Aurora facility approximately 40 miles west of downtown Chicago, but the financial ecosystem that trades against CME infrastructure concentrates across two Chicago submarkets: downtown for firms trading at competitive-but-not-lowest latency, and Aurora specifically for firms requiring absolute lowest latency to the CME matching engine.
Hedge funds, proprietary trading firms, high-frequency trading operations, and clearing firms cluster in Chicago colocation specifically to reduce latency to CME infrastructure. For these firms, sub-millisecond latency is not a preference — it’s the entire business case for colocation. Equinix CH1 and CH2 in downtown Chicago serve this ecosystem, while CyrusOne Aurora and Equinix’s Aurora campus serve firms requiring the absolute lowest possible latency to CME’s matching engine.
CBOE Global Markets (Chicago Board Options Exchange) presents a nuanced Chicago story — while headquartered in Chicago, CBOE’s primary matching infrastructure runs from data centers in Secaucus, New Jersey. Chicago proximity to CBOE administrative and clearing operations still matters for firms with CBOE relationships. See our financial services colocation guide for detailed compliance and infrastructure analysis.
350 East Cermak defines the downtown carrier ecosystem
The Lakeside Technology Center at 350 East Cermak Road is one of the largest single-building data centers in the world at over 1.1 million square feet. Digital Realty owns and operates the building, but multiple providers maintain suites within it. This concentration creates carrier density unmatched by any other Chicago facility — nearly every major internet carrier terminates at 350 E Cermak including Cogent, Zayo, Lumen, AT&T, Verizon Business, GTT, Windstream Wholesale, Comcast, and specialized providers like Level 3, XO Communications, and NTT.
For bandwidth-heavy workloads (streaming, content distribution, media companies, and increasingly AI infrastructure requiring significant data ingestion), 350 E Cermak delivers pricing leverage no other Chicago facility matches. The building also serves as a major peering point for Chicago and midwest internet traffic through the Chicago Internet Exchange (Equinix IX) and other peering fabrics.
The Elk Grove Village and O’Hare corridor is where hyperscale lives
Downtown Chicago colocation gets most of the attention, but the O’Hare corridor — specifically Elk Grove Village and Itasca — is where Chicago’s hyperscale data center market operates. QTS Realty Trust (owned by Blackstone) operates massive Elk Grove Village and Itasca campuses that dominate the Chicago-area hyperscale market. Aligned Data Centers operates significant Northlake facilities. Digital Realty operates its 1500 Lakeside Drive facility in Elk Grove Village (formerly Ascent Corporation) and the 9333 Grand Avenue Franklin Park campus. Iron Mountain, H5 Data Centers, and Stack Infrastructure all maintain O’Hare corridor presence.
The concentration in Elk Grove Village exists because Chicago city permitting and zoning are notoriously complex for large-scale data center construction, while suburban Elk Grove Village and Itasca offer streamlined approvals, land availability, and power infrastructure suitable for hyperscale deployment. Cook County suburbs also offer favorable tax treatment for data center investment.
Chicago’s power economics create genuine cost advantages
Chicago colocation benefits from meaningful power cost advantages versus East Coast markets. Commonwealth Edison (ComEd) commercial power rates run competitive with midwest averages, meaningfully below NYC-area rates. Chicago power infrastructure benefits from proximity to significant nuclear generation capacity operated by Constellation Energy (formerly Exelon), providing baseline reliable power. The regulated Illinois power market provides more predictable long-term pricing than deregulated East Coast markets.
Chicago also benefits from natural cooling advantages during roughly six months of the year (November through April), when outdoor temperatures allow free cooling via air-side economizers or water-side economization. Lake Michigan proximity provides cooling water availability that some facilities leverage. These free cooling advantages produce meaningful operating cost reductions versus year-round mechanical cooling required in warmer climates.
Midwest enterprise buyer profile
Chicago mid-market enterprise buyers differ from NYC buyers in specific ways. Chicago companies tend to be more cost-focused than NYC counterparts, more likely to consider secondary markets (Iowa, Nebraska, Ohio) for backup infrastructure, more focused on long-term contract stability than shorter-term flexibility, and less sensitive to Manhattan-style prestige factors that drive some NYC decisions.
This buyer profile favors value-focused providers like DataBank, TierPoint, and CoreSite over premium-tier options for many workloads.
Argonne National Laboratory anchors the research computing ecosystem
Argonne National Laboratory in nearby Lemont operates Aurora, one of the world’s most powerful supercomputers (an Intel-based exascale system unrelated to CME’s Aurora facility). Argonne’s AI and research computing infrastructure creates a Chicago-adjacent research ecosystem serving academic institutions including the University of Chicago, Northwestern University, and the University of Illinois system. Chicago-area AI research operations often maintain infrastructure relationships spanning research computing at Argonne and commercial colocation for production workloads.
Union labor and construction realities
Chicago is a strong union town, which affects data center operations in specific ways. Physical infrastructure work including cross-connect installation, cabinet work, and any construction involves union labor considerations that don’t apply identically in other markets. This affects both cost and scheduling for facility work. Suburban Chicago facilities and downtown facilities may have different labor arrangements affecting operational flexibility.
Central US network advantages
Chicago sits at the intersection of major US network backbones, making it a natural aggregation point for connectivity between coasts. Firms serving both East Coast and West Coast markets often choose Chicago for primary infrastructure specifically for network topology advantages.
Growing AI and high-density demand
Chicago has become a significant secondary market for AI and GPU infrastructure workloads. High density colocation (30-100+ kW per rack) is available across multiple providers including Digital Realty, DataBank, Equinix CH1, and hyperscale providers QTS and Aligned in Elk Grove Village. For firms deploying dedicated AI infrastructure, Chicago pricing runs meaningfully below NYC while delivering comparable network connectivity.
Compliance Framework Requirements for Chicago
Chicago companies face compliance frameworks that vary by industry but share common infrastructure requirements.
SOC 2 Type II
Chicago's mid-market and enterprise buyers increasingly require SOC 2 Type II attestation from vendors, including colocation providers. All major Chicago providers maintain SOC 2 Type II certification. DataBank Chicago and Digital Realty at 350 E Cermak carry the most comprehensive SOC 2 documentation for enterprise client audit purposes.
HIPAA Business Associate Agreements
Healthcare workloads face HIPAA obligations extending to infrastructure providers. Chicago-area healthcare systems (Northwestern Memorial, Rush University Medical Center, University of Chicago Medicine, NorthShore, Advocate Aurora) require BAA-covered infrastructure for patient data workloads. DataBank Chicago provides the strongest HIPAA BAA capability with HITRUST-adjacent controls. See our healthcare and HIPAA colocation guide for BAA-specific analysis applicable to Chicago healthcare deployments.
PCI DSS
Chicago fintechs, payment processors, and any firm handling card data face PCI DSS obligations. Equinix CH1 and CH2 provide PCI DSS-aligned infrastructure with financial services documentation.
SEC and CFTC oversight for trading firms
Chicago's derivatives trading ecosystem faces SEC (for securities-related activities) and CFTC (for futures and options) oversight. Trading firm infrastructure at Equinix CH1 and CH2 satisfies documented regulatory requirements including record retention and audit capability.
Illinois Biometric Information Privacy Act (BIPA)
The Illinois Biometric Information Privacy Act creates specific obligations for any Chicago company handling biometric identifiers including fingerprints, facial geometry, voiceprints, or retinal scans. BIPA is one of the strictest biometric privacy laws in the United States and has generated significant class action litigation. Infrastructure supporting biometric workloads requires documented controls satisfying BIPA compliance including specific consent, retention, and destruction requirements that extend to infrastructure providers.
Regional compliance considerations
Chicago companies serving national customer bases face multi-state regulatory obligations including California CCPA, New York DFS Cybersecurity Regulation Part 500 (for firms serving NY-regulated financial services clients), Virginia CDPA, and various other state-specific privacy laws. Colocation facility SOC 2 Type II certification supports compliance across these frameworks.
Chicago Facility Comparison
Not every Chicago-area facility fits every workload profile. Here’s how the major facilities compare for buyer decisions.

Additional Chicago Market Context — Hyperscale and Specialized Providers
Beyond the Sandler Partners providers we work with directly, understanding the broader Chicago market provides essential context for any infrastructure decision. The Chicago colocation market includes several specialized and hyperscale operators worth understanding.
QTS Realty Trust operates massive Elk Grove Village and Itasca campuses that dominate Chicago-area hyperscale deployment. Owned by Blackstone since 2021, QTS focuses on hyperscale cloud provider deployments and enterprise wholesale colocation at scale. For firms requiring very large deployments (multiple MW of power, thousands of square feet of white space), QTS represents a significant Chicago option.
Aligned Data Centers operates significant Northlake facilities focused on wholesale colocation and hyperscale deployment. Aligned’s Delta-Cube cooling technology enables higher density than traditional facilities.
Iron Mountain Data Centers maintains Chicago colocation presence primarily focused on records management-adjacent workloads and government contracts.
H5 Data Centers operates as a wholesale colocation provider with Chicago presence.
Stack Infrastructure has been active in Chicago hyperscale build activity with growing capacity.
CyrusOne Aurora serves the ultra-low-latency CME trading firm segment specifically.
We do not maintain direct channel relationships with these operators, but understanding their market presence matters for any complete Chicago infrastructure evaluation. Metro Colo Advisory focuses on Sandler Partners providers (Equinix, Digital Realty, DataBank, CoreSite, Cologix, TierPoint, Flexential) where our channel relationships provide competitive advantages for our clients.

What Chicago Workloads Actually Need
Chicago infrastructure supports specific workload profiles with specific requirements. Understanding what your Chicago deployment actually runs is the foundation of facility selection.
Financial services and CME Group ecosystem
Chicago’s derivatives trading ecosystem (CME Group, CBOE Global Markets, Cboe futures) drives specific infrastructure requirements. Trading firms need sub-millisecond latency to CME’s Aurora matching engine, direct cross-connects to CME PICO connectivity, clearing member connectivity infrastructure, and documented compliance for SEC and CFTC oversight. Downtown Chicago facilities (Equinix CH1, CH2) serve trading firms comfortable with the additional 40-mile network hop to Aurora. Aurora-specific facilities (CyrusOne Aurora, Equinix Aurora) serve firms requiring absolute lowest possible latency to CME infrastructure.
Enterprise infrastructure
Chicago’s Fortune 500 headquarters (Boeing, Walgreens Boots Alliance, Archer-Daniels-Midland, Caterpillar, Kraft Heinz, Motorola Solutions, and others) drive substantial enterprise colocation demand. Enterprise workloads require SOC 2 Type II certified facilities, documented compliance across multiple frameworks, disaster recovery capability with geographic separation, high availability infrastructure with 2N power redundancy, and cross-connect ecosystem to major cloud on-ramps.
For enterprise infrastructure planning, see our colocation site selection framework.
Healthcare and life sciences infrastructure
Chicago’s healthcare ecosystem (Northwestern Medicine, Rush, University of Chicago Medicine, NorthShore, Advocate Aurora) drives healthcare-specific colocation demand. Healthcare workloads require HIPAA Business Associate coverage, HITRUST-adjacent controls, EHR system infrastructure (Epic, Cerner), medical imaging infrastructure requiring high storage capacity, and telemedicine platform infrastructure.
Insurance industry infrastructure
Chicago’s substantial insurance industry (Allstate, Blue Cross Blue Shield of Illinois, CNA Financial, Zurich North America) drives insurance-specific colocation demand. Insurance workloads face regulatory scrutiny from Illinois Department of Insurance, NAIC requirements, and specific compliance frameworks.
Research computing and AI
Chicago’s research computing ecosystem centered on Argonne National Laboratory, University of Chicago, Northwestern University, and University of Illinois drives specialized infrastructure demand. Research computing workloads often bridge national laboratory infrastructure and commercial colocation for production and outreach workloads. The presence of Argonne’s Aurora exascale supercomputer creates a Chicago-area AI research ecosystem that increasingly influences commercial AI infrastructure decisions.
Manufacturing and industrial infrastructure
Chicago’s manufacturing sector (Boeing, Caterpillar, Motorola Solutions, and various industrial operations) increasingly requires colocation infrastructure for IoT data aggregation, predictive maintenance analytics, supply chain visibility systems, and industrial control system backup infrastructure.
AI and GPU infrastructure
Chicago has become a growing secondary market for AI and GPU infrastructure workloads. Firms deploying dedicated AI infrastructure in Chicago face significantly lower costs than NYC or Silicon Valley while accessing sufficient network connectivity and carrier density. For firms with significant AI infrastructure ambitions, high density colocation capability at DataBank and Digital Realty Chicago becomes essential, alongside hyperscale options at QTS and Aligned for very large deployments.
Media and content distribution
Chicago’s media and broadcast ecosystem (Tribune Publishing, various broadcast affiliates, digital media companies) drives media-specific colocation demand. Content distribution workloads benefit from 350 E Cermak’s exceptional carrier density.
Data center migration workloads
Chicago companies executing data center migration or data center relocation projects (from on-premise to colocation, from one facility to another, or cloud repatriation from AWS/Azure/GCP) face specific infrastructure planning requirements. See our data center migration guide for the complete framework.
Disaster recovery infrastructure
Chicago serves both as a primary market and as a DR site for East Coast primary infrastructure. Chicago DR sites for NYC primary deployments provide meaningful geographic separation while maintaining acceptable network latency. See our disaster recovery colocation framework for DR architecture guidance.
What Chicago Colocation Actually Costs
Chicago colocation pricing depends on rack density, cross-connect requirements, contract length, and facility selection. Chicago pricing runs meaningfully below NYC market pricing while delivering comparable infrastructure quality.
Directional Chicago pricing context
Chicago base colocation pricing typically runs 15-30 percent below equivalent NYC infrastructure at comparable providers. Standard density deployments (5-15 kW per rack) at Chicago facilities typically run at value-tier pricing across all major providers, benefiting from Chicago’s power cost advantages via ComEd rates and free cooling economics roughly six months per year.
Financial services deployments at Equinix CH1 and CH2 command premium pricing reflecting CME Group ecosystem access, similar to Equinix NY4 payment network premium in the NYC market. Cross-connects to CME PICO connectivity and clearing member networks add substantially to base colocation costs for trading firm deployments.
Ultra-low-latency Aurora deployments command additional premium reflecting the specialized nature of that submarket.High density AI deployments at Digital Realty 350 E Cermak or DataBank Chicago command premium pricing reflecting specialized cooling and power infrastructure required for 30-60+ kW per rack density. Hyperscale deployments at QTS Elk Grove Village or Aligned Northlake operate at wholesale pricing structures fundamentally different from retail colocation.
For broader colocation pricing context, see our colocation pricing guide.
What we provide instead of specific rates
Specific colocation pricing for your Chicago deployment depends on density, cross-connect requirements, contract length, and facility selection. Metro Colo Advisory provides current Chicago market rate benchmarks for your specific requirements at no cost — including Equinix, Digital Realty, DataBank, CoreSite, and TierPoint rates for comparative evaluation.
Chicago Scenarios We Navigate Regularly
We do not publish client names. But here are the types of Chicago infrastructure situations we handle regularly.
Scenario 1
Chicago Trading Firm Optimizing CME Connectivity
A 45-person Chicago-based proprietary trading firm has been running production infrastructure at Equinix CH1 but is evaluating whether their current cross-connect strategy and rack utilization actually justify the premium pricing. Their CTO wants to understand whether their infrastructure decisions still fit their business given evolving trading strategies, and whether Aurora deployment would meaningfully improve their competitive position.
Our Approach
Review current infrastructure utilization against actual trading strategy requirements. Evaluate whether Equinix CH1 or CH2 is optimal for their specific strategy, whether Aurora deployment justifies the additional cost for their latency-sensitivity, or whether some workloads could move to lower-cost facilities without impacting trading performance.
Model the economics of consolidation, expansion, or facility change across Equinix, Digital Realty, and DataBank Chicago plus Aurora-specific facilities. Handle contract negotiation to ensure competitive pricing on any renewal or new commitment.
Scenario 2
Chicago Healthcare System Building HIPAA-Compliant Infrastructure
A 200-employee regional healthcare organization has been running EHR infrastructure on aging on-premise servers in their downtown Chicago hospital. Compliance requirements have grown, hardware is approaching end of life, and they need to modernize their infrastructure while maintaining HIPAA Business Associate coverage across all patient data workloads.
Our Approach
Design a HIPAA-compliant infrastructure architecture with documented BAA coverage. Evaluate DataBank Chicago as primary infrastructure with HITRUST-adjacent controls appropriate for enterprise healthcare requirements. Consider CoreSite CH1 for cloud on-ramp connectivity to Epic hosted services if applicable. Design disaster recovery colocation architecture with geographic separation from primary infrastructure. Handle the data center migration planning including hardware transition, network cutover, and business continuity during migration.
Scenario 3
Chicago Fintech Escaping Cloud Cost Trap
A 65-person Chicago-based fintech has grown rapidly and their AWS bill has reached $95,000 monthly. Their CFO has flagged infrastructure costs as unsustainable at current growth rate, but their CTO is nervous about cloud repatriation execution risk. They need to understand whether cloud repatriation makes sense economically and what execution looks like.
Our Approach
Run comprehensive cloud repatriation analysis modeling current cloud costs versus dedicated colocation infrastructure at Chicago facilities. Evaluate DataBank Chicago as primary for compliance-heavy fintech workloads, CoreSite CH1 for hybrid cloud colocation architecture maintaining some cloud dependencies, and Equinix CH2 for payment network connectivity if applicable. Design the hybrid cloud colocation architecture supporting appropriate workload placement across dedicated and cloud infrastructure.
Common Mistakes Chicago Companies Make
Five mistakes we see repeatedly in Chicago colocation evaluations.
1. Assuming Equinix is required for financial services workloads.
Equinix CH1 and CH2 are essential for CME Group ecosystem access — trading firms need this. But many financial services workloads (fund administration, back-office operations, compliance reporting, portfolio analytics) don’t need CME latency and pay premium pricing unnecessarily. Understanding whether your specific financial services workload actually needs Equinix ecosystem prevents overpaying for infrastructure you don’t need.
2. Defaulting to 350 E Cermak without evaluating whether you need the carrier density.
Digital Realty’s Lakeside Technology Center is exceptional for bandwidth-heavy workloads, but most enterprise workloads don’t need 100+ carrier options. Firms choosing 350 E Cermak for general enterprise workloads sometimes pay for carrier density they don’t use when DataBank or TierPoint would deliver equivalent infrastructure at meaningfully lower cost.
3. Missing DataBank in initial provider evaluation.
DataBank Chicago has less brand recognition than Equinix or Digital Realty but delivers the strongest overall compliance posture in the Chicago market with meaningful cost advantages. Chicago companies that only evaluate the “big two” miss the provider that often fits their actual requirements best.
4. Overlooking the Elk Grove Village submarket for scale deployments.
Downtown Chicago gets attention, but Elk Grove Village and Itasca dominate Chicago’s hyperscale market. Firms deploying at scale (500+ kW or larger) often achieve better economics in the O’Hare corridor. Chicago city permitting complexity and downtown real estate costs make suburban campuses genuinely more efficient for scale deployment.
5. Not evaluating cloud repatriation economics before committing to cloud-native architectures.
Chicago companies at scale increasingly find that cloud costs exceed dedicated infrastructure by meaningful margins (typically 30-60 percent for stable workloads). Companies committed to cloud-native architectures without evaluating repatriation math sometimes miss the timing to capture available savings.
Five Questions to Answer Before Any Chicago Colocation Decision
The right facility depends on getting five foundational questions right before making any facility commitment.
1. Which Chicago submarket fits your workload?
Downtown Chicago (350 E Cermak, Equinix CH1) serves financial services and carrier-heavy workloads. Elk Grove Village and Itasca (QTS, Aligned, Digital Realty) serve hyperscale and scale enterprise deployments. Aurora serves ultra-low-latency CME trading. Understanding your submarket determines your facility candidate list.
2. Do you need CME Group ecosystem access?
Trading firms, high-frequency trading operations, and firms with direct CME connectivity requirements need Equinix CH1 or CH2. Firms requiring absolute lowest latency may need Aurora-specific facilities. Other financial services workloads may not. Understanding your specific latency and connectivity requirements determines whether Equinix premium pricing or Aurora deployment is justified.
3. What compliance frameworks apply to your deployment?
Healthcare workloads face HIPAA obligations favoring DataBank. Financial services face SEC/CFTC and Illinois Department of Insurance requirements. Fintechs face PCI DSS obligations. Firms handling biometric data face BIPA-specific obligations. Understanding compliance requirements determines the candidate facility list.
4. What is your density trajectory?
Standard density (5-15 kW per rack) is supported by all major Chicago providers. High density (30-60+ kW per rack) requires specific facility capabilities at Digital Realty 350 E Cermak, DataBank Chicago, or Equinix CH1. Hyperscale density requires QTS or Aligned campuses. Understanding your 3-year density requirements affects facility selection.
5. What is your disaster recovery posture?
Chicago serves both as primary market and as DR site for East Coast infrastructure. Understanding whether your Chicago deployment is primary or DR (or should be paired with DR at another location) determines the complete infrastructure architecture.
The Independent Advisory Approach to Chicago Colocation
Chicago colocation evaluations benefit from independent advisory because the variance between marketing claims and actual capability across providers matters more in secondary markets than in NYC. Providers focus their strongest sales resources on their largest markets. Chicago buyers sometimes receive less attention from provider sales teams than NYC buyers, making independent advisory even more valuable.
Think of Metro Colo Advisory like a buyer’s agent in real estate. We work exclusively for our clients, not for the colocation providers. Commission comes from the provider you ultimately choose, paid only when a deal closes, so there’s no cost to you at any stage of the evaluation. Our independence comes from representing the buyer through every step of the evaluation, negotiation, and contracting process across all major Chicago providers, never the seller.
As an independent colocation broker with formal channel partner relationships across Equinix, Digital Realty, DataBank, CoreSite, Cologix, TierPoint, and Flexential, Metro Colo Advisory provides objective Chicago provider comparison at no cost to clients. Our only incentive is placing you at the provider that best fits your specific workload, compliance, and budget requirements. We also maintain working knowledge of the broader Chicago market including QTS, Aligned, and other operators, so our provider recommendations reflect complete Chicago market context rather than limited perspective.

Frequently Asked Questions About Chicago Colocation
What is the best data center in Chicago?
The best Chicago data center depends on workload requirements and submarket. In downtown Chicago, 350 East Cermak Road (the Lakeside Technology Center operated by Digital Realty) provides the strongest carrier density in the Chicago market with over 100 network carriers including Cogent, Zayo, Lumen, AT&T, Verizon Business, GTT, and specialized providers, making it the primary choice for bandwidth-heavy workloads. Equinix CH1 and CH2 anchor the CME Group financial services ecosystem, making them essential for trading firms and financial services workloads requiring low-latency CME connectivity. In the Elk Grove Village and O’Hare corridor, QTS Realty Trust dominates hyperscale deployment alongside Aligned Data Centers and Digital Realty’s Elk Grove Village facility. Among Sandler Partners providers, DataBank Chicago provides the strongest documented compliance posture (SOC 2 Type II, HIPAA BAA, HITRUST-adjacent) for compliance-heavy workloads at 20-35 percent below Equinix pricing. CoreSite CH1 provides Open Cloud Exchange direct connectivity to AWS, Azure, and GCP for hybrid cloud architectures. TierPoint Chicago serves mid-market enterprise with strongest overall value for standard workloads. The right facility depends on your specific workload, compliance, and budget requirements. Metro Colo Advisory evaluates the Chicago facility decision at no cost.
How much does colocation cost in Chicago?
Chicago colocation pricing typically runs 15-30 percent below equivalent NYC infrastructure at comparable providers, driven partially by Chicago’s power cost advantages via ComEd rates and free cooling economics roughly six months per year. Standard density deployments (5-15 kW per rack) at Chicago facilities run at value-tier pricing across DataBank, TierPoint, and CoreSite. Equinix CH1 and CH2 command premium pricing reflecting CME Group ecosystem access, with cross-connects to CME PICO connectivity adding substantially to base costs for trading firm deployments. Ultra-low-latency Aurora deployments command additional premium reflecting the specialized nature of that submarket. High density AI deployments at Digital Realty 350 E Cermak or DataBank Chicago command premium pricing reflecting specialized cooling and power infrastructure required for 30-60+ kW per rack density. Hyperscale deployments at QTS Elk Grove Village or Aligned operate at wholesale pricing structures fundamentally different from retail colocation. Total colocation pricing includes rack fees, power costs, cross-connect fees, and setup costs. Metro Colo Advisory provides current Chicago market rate benchmarks for your specific requirements at no cost.
Why do trading firms choose Chicago colocation?
Chicago is home to CME Group, the world’s largest derivatives exchange, with matching engines at the Aurora facility approximately 40 miles west of downtown Chicago. Trading firms, high-frequency trading operations, proprietary trading firms, and clearing firms choose Chicago colocation specifically to minimize latency to CME infrastructure. Sub-millisecond latency to CME’s matching engine is essential for trading strategies that depend on speed. Equinix CH1 and CH2 anchor the downtown Chicago financial services ecosystem with the deepest cross-connect fabric to CME PICO connectivity, clearing member infrastructure, and other financial counterparties. Firms requiring absolute lowest latency to CME sometimes deploy at Aurora-specific facilities including CyrusOne Aurora and Equinix Aurora rather than downtown Chicago, accepting the tradeoff of reduced financial ecosystem access for latency advantage. Chicago also provides central-US network topology advantages for firms trading across multiple exchanges, and lower operating costs than NYC financial ecosystem infrastructure. Metro Colo Advisory evaluates trading firm infrastructure decisions in Chicago at no cost.
What is 350 East Cermak Road and why is it important?
350 East Cermak Road is the Lakeside Technology Center, one of the largest single-building data centers in the world at over 1.1 million square feet. Digital Realty owns and operates the building. The facility’s significance comes from its exceptional carrier density — over 100 network carriers terminate at 350 E Cermak including Cogent, Zayo, Lumen, AT&T, Verizon Business, GTT, Windstream Wholesale, and specialized providers, creating pricing leverage for bandwidth-heavy workloads that no other Chicago facility matches. Streaming platforms, content distributors, media companies, and any firm where bandwidth economics dominate infrastructure costs benefit meaningfully from 350 E Cermak deployment. The facility also serves as a major peering point for Chicago and midwest internet traffic. Multiple providers maintain suites within 350 E Cermak in addition to Digital Realty’s primary operations. Metro Colo Advisory evaluates 350 E Cermak deployment decisions at no cost.
Where should hyperscale deployments locate in Chicago?
Chicago hyperscale deployment concentrates in the Elk Grove Village and Itasca corridor near O’Hare, rather than downtown Chicago. QTS Realty Trust (owned by Blackstone) operates the dominant Chicago-area hyperscale campuses in Elk Grove Village and Itasca. Aligned Data Centers operates significant Northlake facilities with Delta-Cube cooling technology enabling higher density than traditional facilities. Digital Realty operates its 1500 Lakeside Drive Elk Grove Village facility (formerly Ascent Corporation) and 9333 Grand Avenue Franklin Park campus at scale. Stack Infrastructure and H5 Data Centers also maintain O’Hare corridor presence. The concentration in Elk Grove Village exists because Chicago city permitting and zoning are complex for large-scale data center construction, while suburban Elk Grove Village and Itasca offer streamlined approvals, land availability, and power infrastructure suitable for hyperscale deployment. For deployments of 500+ kW or larger, the O’Hera corridor typically delivers better economics than downtown Chicago facilities. Metro Colo Advisory evaluates hyperscale deployment decisions in Chicago at no cost.
Is Chicago better than Northern Virginia for colocation?
Chicago and Northern Virginia (Ashburn) serve different primary use cases rather than one being universally better. Ashburn is the largest US colocation market with meaningfully more capacity, provider options, and cloud on-ramp density. For firms requiring maximum cloud connectivity or East Coast government contractor infrastructure, Ashburn typically wins. Chicago provides better central-US network topology for firms serving both coasts, CME Group financial services ecosystem access, established midwest enterprise infrastructure, and typically 15-25 percent lower pricing than Ashburn premium tier. Chicago also benefits from power cost advantages via ComEd rates and free cooling economics roughly six months per year, plus proximity to significant nuclear generation capacity. For firms with specific Chicago requirements (CME trading, midwest enterprise presence, central-US network position), Chicago wins. For firms with maximum cloud integration requirements or East Coast government focus, Ashburn wins. Metro Colo Advisory evaluates Chicago versus Ashburn comparison for specific workloads at no cost.
Which Chicago colocation provider is best for healthcare workloads?
DataBank Chicago leads healthcare workload deployments in the Chicago market. DataBank facilities carry the strongest documented compliance posture in Chicago including SOC 2 Type II certification, HIPAA Business Associate Agreement (BAA) capability, HITRUST-adjacent controls, and audit-defensible compliance documentation that satisfies enterprise healthcare client audit requirements from systems like Northwestern Memorial, Rush University Medical Center, University of Chicago Medicine, NorthShore, and Advocate Aurora. DataBank also supports high-density infrastructure appropriate for medical imaging workloads and EHR system infrastructure. Equinix provides SOC 2 Type II with financial services documentation appropriate for healthcare-adjacent financial workloads. Digital Realty provides standard enterprise compliance programs. CoreSite provides SOC 2 Type II with Open Cloud Exchange for hybrid healthcare architectures. For healthcare workloads where compliance documentation depth is a primary requirement, DataBank typically provides the strongest fit. Metro Colo Advisory evaluates compliance-focused provider selection for Chicago healthcare deployments at no cost.
Where should Chicago companies host AI and GPU infrastructure?
Chicago has become a growing secondary market for AI and GPU infrastructure workloads. Firms deploying dedicated AI infrastructure in Chicago face significantly lower costs than NYC or Silicon Valley while accessing sufficient network connectivity. Among Sandler Partners providers, DataBank Chicago supports high density colocation (30-60+ kW per rack) with strong compliance documentation appropriate for AI infrastructure across healthcare, legal, and fintech verticals. Digital Realty at 350 E Cermak supports high-density AI infrastructure with exceptional carrier density valuable for AI workloads requiring significant data ingestion. Equinix CH1 offers high-density support alongside financial ecosystem connectivity appropriate for AI-heavy financial services workloads. For hyperscale AI deployments (multiple MW), QTS Elk Grove Village and Aligned Northlake dominate the market. Chicago’s proximity to Argonne National Laboratory’s Aurora exascale supercomputer creates a research computing ecosystem that influences commercial AI infrastructure decisions in the region. For firms deploying dedicated GPU infrastructure without payment network or CME requirements, DataBank Chicago typically provides the strongest combination of density support and value pricing among retail providers. Metro Colo Advisory evaluates AI infrastructure provider selection for Chicago deployments at no cost.
Is colocation better than cloud for Chicago companies?
For Chicago companies at scale with stable production workloads, dedicated colocation typically delivers meaningful advantages over cloud-only architectures. Colocation advantages include 30-60 percent cost reduction versus equivalent AWS or Azure deployments for stable predictable workloads, documented facility-level compliance for regulatory examinations, direct payment network and CME cross-connect access (impossible on cloud), predictable cost structure without cloud fee scaling as usage grows, and typically 5-year contract stability supporting long-term financial planning. Cloud advantages include elasticity for irregular workloads, faster initial deployment, and reduced operational overhead for smaller Chicago operations. Most successful Chicago companies at scale end up with hybrid architectures — production workloads on dedicated colocation, customer-facing services on cloud, burst capacity on cloud. For Chicago companies with $50,000+ monthly cloud spend, colocation evaluation typically produces meaningful ROI. Metro Colo Advisory models cloud versus colocation economics for Chicago workloads at no cost.

Ready to Talk About Your Chicago Infrastructure Requirements?
Chicago colocation is genuinely complex, with three distinct submarkets (downtown, O’Hare corridor, Aurora), multiple major providers with meaningfully different strengths, and specialized workload requirements from CME trading to hyperscale AI deployment. The right answer for your Chicago deployment depends on workload profile, compliance requirements, budget tier, and specific ecosystem needs. There is no single best facility for all Chicago workloads — the right answer depends entirely on what your infrastructure actually needs to deliver.
Metro Colo Advisory has no financial stake in which provider or facility Chicago clients ultimately choose. We work with growth-stage companies, mid-market enterprise, financial services firms, healthcare organizations, and fintechs evaluating colocation across Chicago and national markets, with channel relationships spanning all major providers and deep expertise in the workload-specific requirements that drive Chicago provider selection.
