Is it just me, or does 200 servers sound like a small number?
When I was in the colocation business, we had lots of customers with over 200 servers just in individual cages (albeit, in cages large than 200 or 300 square feet). Having a 5 story bunker with 200 servers sounds very low-density by comparison. I wonder if they never upgraded power and cooling when the bunker was converted to a bit barn. I suppose that given the nature of the facility it would be pretty hard to upgrade.
