As a small-time webhost, I can tell you this answer is crap. Even little operations such as mine are housed in datacenters with more than enough power. Hell I have sites that have been DoSed, Slashdotted and Dugg - Its driven my operations to a crawl, yet I have never EVER lost power.
I smell a 'repair/upgrade our servers' donation drive- if by chance this is true, there is something very wrong with that hardware if its blowing fuses via overheating.
