Aging distribution plants are have caused lots of problems.  We had an 
18-hour power outage in Oakland (neighborhood just east of downtown 
Pittsburgh) about 10 days ago when two separate 25kV feeders from the 
local substation blew at the same time.  Local utility crews ended up 
having to replace around 400' of fried underground feeder cable.

Our core sites are on redundant power, but in many cases this didn't 
include the chiller plant.  Some of the rooms got hot, but we didn't lose 
any core equipment.

Other large organizations in the area were not so lucky.
