Where can I find a list of Service Providers for Equinix Fabric?

Alternatively, you can also log into Equinix Marketplace and search for all providers.

You can filter to show all service providers, or solely in the right location and/or data center (IBX). You can also filter to display only service provider offering their services via Fabric:

https://marketplace.equinix.com/mkp/search

Access to Marketplace is available for all Equinix customers and partners; guest access can be attained by registering: https://marketplace.equinix.com/mkpportal/en_US/registration

Thanks!

Last possibility, to have a complete view, with filtering by location or Service Provider, head to:
