The DNS recursor servers which are used from inside Cloud VPS and
Toolforge to resolve both internal and external hostnames to IP
address were not functional from approximately 2019-09-09T00:51 UTC to
2019-09-09T01:35 UTC. During this time, most (if not all) DNS lookups
would have returned a "SERVFAIL" response. The issue appears to be
resolved now.
We will share more information about what happened and how the problem
was corrected when we are sure that doing so will not cause additional
issues.
