With a redundant power supply upgrade going on this week in the datacenter that could
affect the VM that Toolsdb runs on, we anticipate a brief outage Thursday 10/24 @11am UTC
of the mysql service to protect data in case anything goes wrong. This may require a
restart of a tool to reconnect to the database. We do not anticipate any worse
disruptions, but if there is any disruption beyond what is planned, a failover may be
necessary, which will not include the non-replicated tables mentioned here

The maintenance requiring this notice and action is detailed here

<https://phabricator.wikimedia.org/T227540>. The VM resides on the cloudvirt1019
hypervisor, which is why it is in scope.
We sincerely apologize for the short notice.
