Seattle Internet Exchange
The Seattle Internet Exchange (SIX) is an Internet exchange point in Seattle, USA. Its switch fabric is centered at the Westin Building and extended to KOMO Plaza, Sabey Intergate, and other locations. The SIX is one of the most successful examples of neutral and independent peering points, created as a free exchange point originally sponsored only by donations. The SIX is the most frequently cited model upon which other neutral Internet exchanges are based, and its financial and governance models are often cited as inspiration for other exchanges. It continues to run without any recurring charges to the participants and current major funding comes from one-time 10, 100, and 400 Gbit/s port fees, as well as from voluntary contributions from stakeholders. The SIX is a 501(c)(6) tax-exempt non-profit corporation.
