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....

Maybe time to co-locate some stuff to a third party data center that can scale up with your demand?
