Sealand's got a lot of problems.

Their sovereignty is questionable. It started out in the 60's as a site for pirate radio. It's never been recognized by any country as a sovereign state. It's well inside Britain's territorial waters. There's been a number of court rulings against it. Wikipedia's got some good background on the "country", including a pic (yeah, that's Sealand!).

They use a lot of "co-location" with most servers located in GB and the US. In an interview in '03, the old CEO stated, "HavenCo's security is primarily due to tamper-resistant hardware and cryptography, not the site security of Sealand." You can implement that anywhere. Lots of material from that interview here:

Obviously, HavenCo in Sealand is not much of a data center in and of itself. And given Sealand's "pirate" profile, I'm not sure HavenCo's the way to go if you want a low profile.
