"The Bunker" is touted as one of the most secure datacenters in the UK, in terms of both physical and information security.
Built in a nuclear bunker decommissioned by the Ministry of Defence (MoD) in the 1990s, the site in Kent can purportedly survive even the most lethal weapons of mass destruction.As well as being underground, the bunker is encased in walls three meters thick, enough to absorb any explosion. The 18-acre site is surrounded by fencing three meters high, topped by a sprawl of barbed wire. Drivers must park outside the property and pass through this barrier. The security point at the barrier, fronted by bullet-proof glass, is manned on every day of the year by ex-police and ex-MoD guards.

The generators should be protected underground also. If connection to grid is impacted, the backup generators would be prime target and the single point of failure for power.
That was the first thing I thought too when I saw those generators... all that security won't mean a thing if someone can blow up the generators and cut the power, rendering the entire facility useless.
Just think about it guys. This is an ex-nuclear bunker. Don't you think *it* would have had reserve power? And it certainly wouldn't have been stuck on top in a couple of containers. There are a number of other published facts that don't ring true. Why two 11kv power supplies? No data centre on earth requires that sort of power. OK, I know it's meant to be secure, but guard dogs? Perhaps they're not disclosing the whole story publicly? Security also sometimes means secrecy. But I rather think it's something more than your average web site host!
