The SIX Core switches are located at KOMO Plaza, Sabey Intergate, and the Westin Building.

The KOMO Plaza uplink is 2x400G soon rising to 3x400G. The Sabey Intergate uplink is 3x100G.

If you would like to colocate at these facilities, some of the possibilities are listed below.

If you need a consultant for BGP & peering help, some of the possibilities are listed below.

There are also 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 SIX Core, as described here, if able.

Connecting to the SIX

Port fees for the SIX Core:

  • 1GbE:
    • KOMO Plaza & Sabey Intergate & Westin Building: One-time/NRC $100. There is no MRC.
    • Guideline on second 1GbE port is that if peak usage is less than 50% of present capacity there is a one-time $500 port fee, otherwise one-time $100. Additional 1GbE ports are each a one-time $1,500.
  • 10GbE:
    • KOMO Plaza & Sabey Intergate & Westin Building: One-time/NRC $1,500. There is no MRC.
  • 100GbE (and 40GbE):
    • KOMO Plaza & Sabey Intergate & Westin Building: One-time/NRC $7,500. There is no MRC.
  • 400GbE:
    • KOMO Plaza & Westin Building: One-time/NRC $15,000. There is no MRC.
  • Upgrades: Generally an upgrade will involve a new LOA since fibers are pre-wired to specific switches/ports capable of specific speeds.
  • MRC option: For port fees that are a one-time $1,500 or higher, we provide an MRC (Monthly Recurring Charge) payment option for those organizations who prefer a lower initial payment and/or want to additionally support the SIX. 10 month minimum commitment with monthly fee at 12% of one-time port fee. At member request, invoicing beyond the 10th month is available to those members who wish to contribute to the SIX.
    • 10GbE: $180/month, 100GbE: $900/month, 400GbE: $1,800/month
  • Port fee is determined by fees current on the date of LOA issuance or port configuration by SIX admins, whichever is earliest.
  • The SIX mailing address is:
    • Seattle Internet Exchange
    • 1700 7th Ave Ste 116 PMB #400
    • Seattle, WA 98101-1323
  • Payment can be via check to the above or via PayPal (paypal_a_t_seattleix.net). If PayPal please add 5% as needed to cover the PayPal fees. We can also invoice and provide wire-transfer details.
  • If you decide to give additional money, you will be recognized on the contributors page for your added donation. The SIX exists because of donations.

Extensions: The SIX charges a one-time/NRC $100 when you connect via an extension. Beyond that, port fees for extensions are determined by the extension operators. Contact them for details.

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

  • Circuit to the SIX Core at KOMO Plaza, Sabey Intergate, or the Westin Building:
    1. Send an e-mail to info_a_t_seattleix.net indicating your interest in connecting at KOMO Plaza, Sabey Intergate, or the Westin Building, your carrier/provider/colo, and specify the port speed. Also let us know if you will participate on the 9000-byte MTU VLAN and thus require a tagged port.
    2. We will confirm fees with you and issue an invoice and/or LOA as appropriate.
    3. You or your colocation provider may then run a cross-connect to the SIX panel.
    4. We will send instructions describing test procedures followed by address assignment.
  • Circuit when using one of the extensions:
    1. Due to the way in which each additional extension operates, you will need to contact the operator of the extension you are interested in.
    2. Send an e-mail to info_a_t_seattleix.net indicating which extension you have chosen. Also let us know if you will participate on the 9000-byte MTU VLAN and thus require a tagged port.
    3. We will confirm fees with you and issue an invoice as appropriate.
    4. We will work with the extension and will send instructions describing test procedures followed by address assignment.

While waiting for your circuit, please review the router configuration advice here. Configure your router and SIX-facing interface accordingly. Also be sure to create or update a PeeringDB.com account.

After you are connected and have your router configured with the IP addresses, you are encouraged to contact the current participants about peering.

Don't forget to read and follow the rules!

If you have any questions let us know at info_a_t_seattleix.net.
