Update 11:01am: The upstream issue seems to have resolved, and sites are again accessible. We'll be monitoring the situation to see if it remains stable.
Authentication to all sites is currently down due to a failure in our central authentication system.
Existing instances should be unaffected, but users won’t be able to create or modify existing instances.
This seems to be caused by a failure in our upstream DNS provider, we are working with them to get an ETA for resolution.
