<hehe> Yeah, they're warmer. All that empty concrete encapsulated space gets
damned cold. Older COs have a lot of empty space where the frames used to be
mounted and they were mostly concrete buildings. The 5ESS' look lonely in
there. Even the battery pile doesn't look as impressive.

As others have said earlier. There is no set standard taxonomy as to what
constitutes a class A datacenter. My definition includes multi-homing, 5-day
backup power, and NEBs, as a start ... finishing off with a five-nines plus
track-record.
