Hello,
Tuesday 17th at 09:00 AM UTC we will be restarting db1132 as part of T239791. We will take the opportunity to upgrade MySQL there.
m2 holds the following databases:
- OTRS - Recommendations API - Reviewdb (gerrit) - Debmonitor
We expect read-only time to be around 30-60 seconds, also, gerrit might be unavailable as well. Coordination will happen on #wikimedia-operations
Thanks! Manuel.
