[c-nsp] Multiple power supply failures. Advise needed

[Scott Granados]

Are these random events?  Have you mapped the failures against any sort of 
power testing / maintenance that the provider is conducting?  We used to 
blow power supplies in an XO facility in San Francisco and found out after 
some digging that their power folks were crack smokers, not professionals 
and were the actual cause of the failures  You might also want to make sure 
the backup power is sized properly.  I have a client now that lost several 
6500 supplies after a power failure in the bay area because their UPS system 
went crazy under far to much load.  Sounds like transients to me!
