An entirely surprising side-effect of this maintenance is causing
chronic database instability. We're working to resolve this but in the
meantime the tools database server is likely to be up and down several
times. We'll update once things are stable again.
Sorry for the (ongoing) interruption!

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
. The VM resides on the
cloudvirt1019 hypervisor, which is why it is in scope.
We sincerely apologize for the short notice.
