Wikileaks began registering sites that can become official "censored" mirrors of the project. Help is accepted from all who agree to donate a little hosting.
The procedure for creating an official mirror is described in detail on a special page . You need to create an account where the site administration can copy files (preferably via RSYNC + SSH), create a host like wikileaks.yourdomain.com and send the administration IP addresses of servers and the path to the directory where to download the content. To then get to the official list of mirrors, you need to exchange open SSH-keys and fill out the form.
