So, can I put you down as being willing to donate the $2.5 million necessary to increase our power capacity (I'm looking out the door at two of our four 1MVA 12.4KV to 480/277 transformers (that we, not the utility, own), and any upgrade will involve the incoming buried primary) and get a couple or three more Mitsubishi 500KVA units?  No?  It's a great tax writeoff, being that we are a 501(c)(3) public not-for-profit foundation.....we'll give you a nice tax receipt.  :-) Oh, and the $1.2 million for an additional 100 tons of redundant HVAC while we're at it....

It's not a surprise, it's just more cost than just the servers themselves, and budgets are tight.
