The Westin Building  is a major telecommunications hub and carrier hotel facility located in downtown Seattle, Washington. The building got its name from the Westin hotel that made its home there when the building was first completed. It is also home to the Seattle Internet Exchange (SIX)  and Pacific Northwest Gigapop's Pacific Wave Exchange.
The facility has a pair of "Meet-me Rooms" on the 19th floor, which are used by telecommunication carriers and internet service providers to cross-connect their individual networks. These carriers situate their POPs within racks spread throughout the building utilizing optical fiber cabling back to the meet-me room thereby facilitating interconnection with other carriers' infrastructure within the building. The Westin Building's meet-me room is the heart of the facility, where buyers and sellers of broadband services offer interconnectivity to their backbones and diverse services without the need to utilize telephone company provided interconnections.
