Seattle Data Center Fire Gets Redundant > Webhosting on the cheap.

said by Mr Matt:

I worked for a web hosting company that designed their backup power system on the cheap. They installed one large generator (about 1.5 Megawatt) to power the entire building. I recommended three generators, one or two of which could power the entire operation in case the third was down for maintenance.

After I left the company, a major hurricane alerted the company that I was right. The facilities manager had significant problems keeping their generator up and running for the two weeks it took to restore commercial power.
