FYI Telehouse Europe in London which hosts LINX (London Internet Neutral
Exchange) provides AC power by default (doubtless they will do DC
power if you ask). They are both an FM facility for dealing rooms
etc., have several colocated telcos, and lots of ISPs. We haven't
(to my knowledge) had a single AC power failure since we've been there.
They have the entire building UPSed with 2 very large glycol generators
and enough fuel to last for at least 3 days. It's possible to do, and
it works. And the price is from memory cheaper than MAE-East.
Telehouse NY (same people) are also starting an IXP. It will be interesting
to see how they compare.
