Having a bit of the past in the business, I must say this is hard core. Also 
not usual that something relatively prosaic like a filed AC unit is the 
cause of the problem. The biggest challenge in the datacenter we had at the 
company where I worked in the Netherlands was how to get enough reliable 
power and how to get rid of the resulting heat.

And it goes without saying...thanks a million to you for doing this for all 
of us.

Cheers,
Nathan
