= phenomenon =
I would like to download the F12 x86_64 DVD iso from http://download.fedoraproject.org/pub/fedora/linux/releases/12/Fedora/x86_64/iso/Fedora-12-x86_64-DVD.iso
Sadly it seems to always redirect me to this URL, which would be ok, if I did not get a 403 Forbidden error: http://sunsite.informatik.rwth-aachen.de/ftp/pub/Linux/fedora/linux/releases/12/Fedora/x86_64/iso/Fedora-12-x86_64-DVD.iso
= reason =
I guess the mirror admin did some misconfiguration.
= recommendation =
The mirror should be removed and there should be some fallback mechanism, e.g. when there is the same request done from the same host within a short interval, it can be asumed that the mirror the host was redirected to does not work and then another mirror is redirected to.
It looks like the web server doesn't have large file support and gives a 403 on large files like the DVD ISO.
The solution would probably be to add a redirect to FTP as described at http://fedoraproject.org/wiki/Infrastructure/Mirroring#Redirecting_ISO_downloads_to_FTP
CCing mdomsch - Does the crawler currently favor HTTP or FTP when checking directories? Is there anything we can do to catch this issue more often?
Reinhard, can you investigate? Looks like your apache can't serve DVD images which are >2TB in size. the workaround is noted here in the links above.
This was fixed by Reinhard with a change to redirect ISOs to a different server running newer apache that they were going to move the whole archive to.
