Gambling on power: Learning lessons

The power at the Bellagio failed for about three days. The failure
involved about 1,000 feet of internal primary power cable. Although
the Bellagio had emergency and backup power, because it was an internal
cable, the backup generators couldn't supply power either. The Las Vegas
Sun has one of the best general media coverage I've seen of a technical
issue involving power failures.

Some data centers and colo facilities would be vulnerable to the same
type of problem. Its difficult and expensive to protect against
everything in a single location. Geographic diversity is almost always
and advantage.

   The power outage that shut down the Bellagio and caused the evacuation
   of thousands of employees and customers could happen at any resort on
   the Las Vegas Strip and at any time, Clark County's top building
   inspector said Wednesday.
