The Westin Building Exchange: Seattle’s Carrier Hotel
The Westin Building, now the Westin Building Exchange, is a 34-story tower at 2001 Sixth Avenue, built in 1981 as the headquarters of Westin Hotels and converted to a carrier hotel in 1995. It is the main interconnection hub for the Pacific Northwest, linking Canada, Alaska and Asia, with connections to trans-Pacific cables including Hawaiki and Southern Cross. Digital Realty, which had owned half of the building since 2006, bought most of the remaining stake in 2020 and now owns about 99%. Inside are the Seattle Internet Exchange and the Pacific Northwest Gigapop, more than 200 telecom, internet and service providers, and data centers run by Equinix (SE2), DataBank (SEA1), Hivelocity and others. Heat from its data centers has been piped to warm Amazon’s neighboring campus. See Digital Realty data centers, Equinix data centers and data center connectivity.

Other Seattle Data Centers: Equinix, Digital Realty and TierPoint
Equinix Seattle runs SE2 inside the Westin Building, SE3 next door, built to seismic Zone 3 standards, and SE4 about 16 miles south. Digital Realty Seattle runs SEA10 in the Westin Building and SEA11 at 2020 Fifth Avenue. TierPoint Seattle sits at Fisher Plaza, a downtown telecom hub at 140 Fourth Avenue North, with a second Washington site in Spokane; together they total about 48,500 square feet and are built for high-density colocation, with low-latency links to the Westin Building and Spokane’s carrier hotel at 422 West Riverside. For colocation, Seattle enterprises replacing an in-house server room usually find that a hall near downtown with a cross-connect to the Westin gives the best balance of cost and connectivity. See disaster recovery colocation and hybrid cloud colocation.

Quincy and Central Washington: The Hyperscale Market
Quincy, in Grant County, is Washington’s hyperscale hub. Microsoft, Yahoo, Intuit, Dell, Vantage and Sabey located there for its competitive electricity rates and fiber, and Moses Lake and Wenatchee have drawn similar projects. The Microsoft Quincy data center campus is the best known; Vantage and Sabey run large campuses in Quincy as well. For a colocation buyer, Quincy matters mainly for large, power-heavy deployments; most cabinet-to-megawatt requirements are better served in Seattle, close to the networks. See wholesale colocation and AI and GPU colocation.

Washington Data Center Tax Rules
| Current rule | |
|---|---|
| Two exemptions | Washington offers a sales and use tax exemption on eligible servers and power infrastructure for data centers in rural counties, and a limited urban pilot program |
| 2026 change | ESSB 6231, effective July 1, 2026, narrowed both: replacement server equipment is no longer eligible, and new exemption certificates for refurbishments are no longer issued |
| What it means | Refreshing servers in an existing data center now carries Washington’s 6.5% state sales tax |
Sources: Washington JLARC, Washington Department of Revenue.
What matters for a colocation tenant: the exemption applies to qualifying data centers and their eligible equipment, not to every tenant purchase, and server refreshes are now taxed. Factor that into the total cost of a multi-year deployment. See data center cost.

Seattle Colocation Pricing
Seattle pricing turns on how close you need to be to the Westin Building. Space inside it carries a premium for direct access to its networks and the Seattle Internet Exchange; halls next door or at Fisher Plaza can reach the same networks over a cross-connect for less, and sites south of the city and in Spokane usually cost less for the same power. Power per cabinet, term and cross-connects decide the rest. Providers do not publish list prices. Compare what you are offered with the ranges on our colocation pricing guide, and for a megawatt or more see the terms that matter in a data center lease.
