Server downtime

I would like to apologize for this morning outage ( 15-08-2011).
We turned off the sta1 server to replace the array card battery, this operation took 15 minutes, but when the server came back
it seems that the Mysql replication got broken and only a full re-setup of the master-master architecture made it working again.
Since we re-established the Mysql replication from a backup certain units could failed the reporting, making the units to not appear in their accounts on cp.mios.com or in their iVera app .
Waiting for another report or power cycling the unit should force a new report from the unit to our servers.
