http://gnuzilla.gnu.org/filters/ is up again.
However, https://gnuzilla.gnu.org/ is not mirrored to
http://gnuzilla.gnu.org/filters/, instead it reads:

This is a mirror of some of the free distributions
<http://www.gnu.org/distros/free-distros.html> we list on
gnu.org/distros and a few other large data sets (e.g., the FSF
membership card, Ryzom artwork). Feel free to download or mirror the
distros from there, preferably using rsync. While we provide copies of
these distros for you for convenience, they are put together and
maintained by others and are outside our control.
If you are maintaining a free distro, please contact FSF sysadmin
<mailto:sysad...@gnu.org> to have your distro mirrored here.
