Find secure, scalable space inside the Pacific Northwest’s principal interconnection facility.

With data centers on four floors, Colocation Northwest is one of the largest retail colocation providers in the Westin Building Exchange building. Located in downtown Seattle, adjacent to Amazon's brand new headquarters and office towers, the Westin building serves the Pacific Northwest as its regional carrier hotel. Host to over 250 networks, carriers and ISPs, this is one of the most connected buildings in the world.





Many features set our downtown data centers apart. Some users like being able to walk to their colocated hardware, Others prefer to use our managed services and let Colocation Northwest handle monitoring, maintenance and repairs, so their admins can focus on their product.

The combination of scalable space, up to 10 kilowatts per cabinet and being inside a major carrier hotel makes downtown Seattle perfect for colocating private, hybrid or multi-cloud infrastructure.


Colocation Northwest operates four data centers in the Westin Building Exchange. Located alongside downtown businesses and hotels, users can have 24-hour access to their equipment or contract with us to manage your IT infrastructure.

  • 2 data centers totaling 4,000 ft2
  • Inside the regional carrier hotel

Once the corporate headquarters for Westin Hotels, over the years the building has added infrastructure and routinely upgraded to support diverse offsite communications, extensive in-building communications and building-wide facilities. This includes the in-wall optical fiber and standby generators that provide power during municipal outages.

Each Colocation Northwest data center has a 1,200-kilowatt capacity. In addition to the building's generators, Colocation Northwest manages the electricity, provides uninterruptible power supply and operates the cooling. They have pre-action fire suppression, smoke and heat detection, and are remotely monitored 24 hours every day from our network operations center.
