Seattle Internet Exchange

The Seattle Internet Exchange (SIX) was originally established in April 1997 as a private interconnection between two ISP's in Seattle's Westin building, whose traffic was traveling from Seattle to Texas and back just to cross from one side of the floor to the other. Starting in June 1997 other ISP's became interested in interconnecting, and the SIX became active June 20th, 1997. Networks began to participate in the SIX due to the low/no cost involved, and it began to grow. The SIX offers GigE, 10GbE, 40GbE, and 100GbE port options. One-time port fees are detailed on our join page. The SIX does not charge recurring fees, but they are offered as a payment option.
