On Thursday we will be migrating most toolforge databases to a
new server. This will take
place on Thursday at 17:00UTC. During this window ToolsDB will be
read-only and most tools that rely on writing to the database
will fail.
This
migration should take about an hour but unexpected side-effects
may extend the downtime.

DB
outage Thursday: As part of
the ongoing effort to upgrade
user-created Toolforge
databases, we will
migrate ToolsDB to a new VM that will have a more recent version
of Debian and MariaDB and will use a more resilient storage
solution.
The
new VM is ready, and we plan to point all tools to use it on Apr, 6 2023 at 17:00 UTC.
This
will involve about 1 hour of read-only time
for the database. Any existing database connection will be
terminated, and if your tool does not reconnect automatically
you might have to restart it manually.
An email
will be sent shortly before starting the migration, and when
it's finished.
Please
also make sure your tool is connecting to the database using the
canonical hostname tools.db.svc.wikimedia.cloud
and not any other hostname or IP address.
