Several people have asked on IRC and Phabricator if the deprecation of
*.wmflabs names for Cloud VPS instances means that the service names
used to connect to ToolsDB and the Wiki Replicas are changing. The
answer is no, these names are not changing yet. We will be replacing
these service names eventually, but for now they are staying in the
wmflabs pseudo domain.
In 2017 [0] we established new canonical service names for accessing
the shared database servers for the Cloud Services environment. Those
names are still the same today.
The naming convention for connecting to the Wiki Replica servers is:
"<wikidb>.{analytics,web}.db.svc.eqiad.wmflabs". The
*.web.db.svc.eqiad.wmflabs service names are intended for queries that
need a real-time response. The *.analytics.db.svc.eqiad.wmflabs
service names are intended for batch jobs and long running queries.
See the announcement from 2017 for more details [0].
The preferred service name for ToolsDB is tools.db.svc.eqiad.wmflabs.
