It seems to have been an outage on a distribution feed to a UPS which 
supplies various servers. The UPS then happened to fail, causing a surge 
on the power line to the servers. Some servers didn't like the surge and 
suffered damage.

The probability of all this happening is low, but not zero.

Risk analysis is only the start, you also have to do the planning for 
if/when it happens.
