Hi
I also set up mirroring of the repositories on repo.or.cz. It is read only mirror, but in case SF.net will have any troubles, there will be always up to date copy available:
http://repo.or.cz/w/phpmyadmin.git http://repo.or.cz/w/phpmyadmin-website.git http://repo.or.cz/w/phpmyadmin-localized-docs.git
...and so on
