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 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.
