Investigate if we can remove AllEndpoints, or update it.

This list of endpoints is 37 entries long. Missing ~6 of our endpoints.

Seeing as the cmdline returns all 43 instances it's clearly retrieving the endpoint list from GCS. It's possible this is only a fallback and could be cleaned up or removed.
