In order to enable report_host flag (T266483) on m5 master (db1128), we need to restart its MySQL.
This host currently has the following active databases:
labsdbaccounts labswiki striker test_labsdbaccounts testreduce testreduce_vd
When: Thursday 28th January at 09:00AM UTC
Impact: The above databases (including wikitech) will be unavailable for a few minutes (no reads/no writes)
This is just a daemon restart, so it shouldn't take too long, maybe a couple of minutes.
