One of our primary ftp mirrors is ftp.ibiblio.org

On Tuesday, March 8, 2011 they will be migrating services to a new server farm and will be offline (possibly for the entire day, or until whenever they are finished.)

If you can't get something downloaded next Tuesday (or perhaps any other day), just try another mirror. :-)
