In order to enable report_host flag (T266483) on m1 master, we need to restart its MySQL.
This host currently has the following active databases:
bacula bacula9 cas cas_staging dbbackups etherpadlite librenms pki
When: Thursday 21st January at 09:00AM UTC
- Impact: The above databases will be read only**
This is just a daemon restart, so it shouldn't take too long, maybe a couple of minutes of read-only time once the proxy has failed over to the read-only replica.
