Joining the SIX

The SIX is located in Seattle's Westin Building.

If you would like to become a tenant of the Westin Building, the phone number is 206-443-1800. If you would like to colocate in the Westin Building, some of the possibilities are listed below.

There are a number of extensions connected to the SIX core fabric. The participants web page indicates how each peer is connected. We recommend that you connect directly to the core, as described here, if able.

Connecting to the SIX

  • Establish your link to the SIX Core (or one of the extensions):

  • Supply Interface SFP / Submit Port fees for circuits to the SIX Core:
    • For GigE, you will need to provide:
      • An SFP (Cisco GLC-LH-SM or compatible) or for $100 we will provide one for you.
      • There is no port fee from the SIX for your first GigE port.
      • General guideline on an additional GigE port is that 50% peak usage of present GigE capacity or a $1,000 one-time port fee of cash or equivalent, will secure a participant an additional GigE port.
    • For 10GE you will need to provide:
      • An SFP+ (Arista 10GBASE-LR or compatible) or, as an additional way to support the community, we can provide an SFP+ for your circuit for $1,000.
      • $5,000 one-time port fee of cash or equivalent per 10GE port.
    • The SIX mailing address is:
      Seattle Internet Exchange, Inc.

    • Payment can be via check to the above or via PayPal (paypal _a_t_ seattleix.net). If paying by PayPal please add 4% to cover the PayPal fees.
    • If you decide to give additional SFPs/SFP+s or additional money, you will be recognized on the contributors page for your added donation. The SIX exists because of donations.
