The claim from this not-utterly-reliable source is that WikiLeaks to move servers offshore, maybe to Sealand.
I’m prepared to believe they are scouting for new locations, including maybe something ocean-based (although how you get adequate connectivity, I have to wonder), but I am quite dubious about the claim that they might go to “Sealand” the oil-derrick-based would-be micronation, since HavenCo I hear is basically collapsed. It would be interesting if it happened, though. For a good account of Sealand, see James Grimmelmann, Sealand , HavenCo, and the Rule of Law.
Meanwhile, count me in with the debunkers at Slashdot.
