Good news is our mirror server fail over worked.
Bad news is it took 30 minutes to get its self sorted
out. During which time the web sites were live but you could not access since the db behind them was over thinking the situation.
We are investigating both why it failed over as well as
why it took so long to complete.
Data was preserved. You should not experience any issues.
The primary server was restarted during this period and
we are back online.
