Where can I find a list of available locations for Equinix Fabric?

Try this link:

https://encap.corp.equinix.com/#/dashboard/Global/all/all

It will give you a list of locations where Fabric is, also EC, Metro Connect, NE by Metro.  It also allows you to see the ports that are available, 1G, 10G, 100G.

Hope it helps!

Thanks
