We need to replace the current primary database master for Commonswiki.
This host is old and out of warranty, so needs to be decommissioned.
We would need a 15 minutes read-only window for Commonswiki.
Date: Tue 26th January
Time: 07:00AM UTC - 07:15 AM UTC (if everything goes as planned we would not use the 15 minutes window)
Impact: Commonswiki will go read-only. No edits/uploads will be allowed. Reads will not be impacted.
