On Thursday we will be migrating most toolforge databases to a new
server. Thiswill take place on Thursday at 17:00UTC. During this window
ToolsDBwill 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 effortto upgrade user-created
Toolforge databases, we willmigrate 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.
