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.
Reminder, this is happening in a few minutes!
