A single level 4 datacenter is a Single Point of Failure!
Two of those middle-eastern style facilities is... ?
Has anyone actually kept track of all these data center failures over
the years and done some statistical analysis on it? Maybe two half-baked
data centers is better than one over the long run?
Remember that one 10-12 years ago in (Palo Alto, Mountainview?) where a
lady in a car caused a backhoe driver to move out of the way which
resulted in him cutting a gas line which resulted in the fire department
evacuating the data center, cutting off electricity in the area, and
forbidding the diesel generators to be switched on?=20
