[Woc-notify] Power restored, was: ITC losing power

[John Unekis]

At approximately 19:00, power from Pepco appears to have been restored. 
However, once again, the transient associated with the power outage blew 
a fuse in the main ITC service panel. The fuse was replaced, and at 
approxiamtely 19:45 the ITC transitioned from generator back to street 
power. Network connectivity has been re-established, and most servers 
are up and functioning.
