A beautiful mind writes "WikiLeaks is asking for hosting space on Unix-based servers. The replication is implemented by a rsync+ssh based push that copies static files to a known path, authenticated via the private half of this public key. The complete website is a few GB in size, making it feasible to replicate on a large scale. The mirror list will be published when the number of independent mirrors reaches 50."
Note: wikileaks.ch seems to be down for the moment, but eventually the above links may require that instead of 184.108.40.206. See also this WikiLeaks address finder
