Topology & Extensions

The SIX topology consists of a set of core switches managed by the SIX ops team, along with a number of extension switches (extensions) operated by third-parties, sometimes with assistance from the SIX ops team.

It is recommended that you connect directly to a core switch, if able. Instructions for doing so are here.

Extensions may charge participants to connect. Contact them for details.
