At this point, rsync and database services should be fully restored on osmdb.eqiad.wmnet,
which now points to osm.db.svc.eqiad.wmflabs (the cloud internal address of the instance
it now runs on).
Work will continue to get the replica in cloud up and running as expected, but that should
not impact users of the server at all.
Apologies for the less smooth transition. I’ll add docs and/or technical fixes to make
future failover more smooth.

Sadly, there was a permissions issue that caused a brief crash during the promotion of the
server to master. The server should be up in read-write mode now on the new server.
Adjusting things to get the rsync jobs moved and working as well at this point.

The OSM postgresql database service, usually accessed via osmdb.eqiad.wmnet is moving to a
new server. Currently the server is a read replica of the primary database, and should be
accessible via the DNS alias of osm.db.svc.eqiad.wmflabs.
As detailed here
https://phabricator.wikimedia.org/T219652, osmdb.eqiad.wmnet will be
changed to point at the osm.db.svc.eqiad.wmflabs. For a brief time that will make those
tables that aren’t always read-only also read-only while DNS updates. Then the replica
will be promoted to the master, and the rest of the steps should not cause any impact.
