Speaking on Deep Background, the Press Secretary whispered:
Hello all.
A company I work with (who's servers are located in the San Jose, CA) is
looking to setup some backup servers at a datacenter whose connectivity and
location is off any faultline, or away from other malady, that might effect its
main servers datacenter or connectivity. Problem is, they also want them as
physically close as possible.
Havenco is a shell of what it once was, and about 75-90% of what it says
on the website isn't true anymore which is sad.
If you're really keen on former british millitary installations turned
colo, there's a company that sells colo in bunkers in the UK 
If we're thinking of the same company its XTML/Telenor/Nextra/GXN/Pipex (or
whatever its called this week
Theyre the most well known that I'm aware of and they have an underground former
bank vault but it'll cost you a fair bit
Theres a few others not so well known who have underground colos (not
necessarily bunkers).
My experience of basements is that they have issues when it rains heavily so I'm
not that keen

http://www.thebunker.net is the one that comes to my mind when I think of
"ex millitary, bomb proof colo facility".

Hmm.. "any other malady". Where is Havenco going to be when the polar ice
caps finish melting?

Does anyone actually know of any machines hosted on HMS Roughs[1]? www.havenco.com is not, it appears. Of the 3/4 NSes listed in whois for havenco.com, only two are operational, one is the machine as www.havenco.com, the other is in havenco's own RIPE assignment (as are the two inoperative NSes).

regards,
PIPEX ServerBank and thebunker.net do seem to be the most widely known
'nuclear-proof' secure datacentres, but there are others out there.
The big gotcha seems to be getting the electrics, cooling and being
on-net to multiple fibre providers to match the physical security.
Thats where most of the others don't score so well IMHO, excepting
the host of government/finance/etc facilities that don't sell space
to anyone anyway.
Not exactly a plug as it is in a different area, but SpringNet offers colo
underground. And everything is underground including generator and
cooling towers. A division of the municipal utility so power is pretty
good also.
