Oh, Alaska is OK and (free) cool dry AIR is DEFINITELY ok;-)
I'd be interested in the routing and bandwidth issues (if any)
associated with an Alaska-based data center serving East-coast
businesses. West too, actually. I count 18-20 hops to e.g. the
University of Alaska at Fairbanks from Duke, with a ping time of around
150-200 msec (vs a typical value of 50-60 for harvard or clemson and
25-30 for a ping to e.g. www.unc.edu 8 miles away).
A fabulously cheap-to-run air-cooled server cluster isn't going to be
very useful if its servers are bottlenecked at any of 16-20 intermediate
network hops. Network topology and distance matter.
Probably be good for Silicon Valley businesses, but if it were TOO good
(i.e. profitable) somebody would just stick a heat exchanger into the
water off of California and use it to cool air and provide the service
