Comment (by mojca@…):

 I wasn't talking about moving the git repositories. I meant situations
 when the server is not accessible for several days. Or when the sources
 disappear completely (there are certain tar.gz files that are only present
 on MacPorts mirrors and can still be installed, but are otherwise long
 gone from web).
