Link not working

[Logan Rah]

the link to the Bit torent of the 3.1r5 doesn't seem to be working, on any
of the different architectures. Although i have found a link for 4.0r0 which
is not stable yet according to the main debain news site. if you can help
that would be cool. the link i am trying to use is
http://cdimage.debian.org/debian-cd/3.1_r5/i386/bt-cd/ but it just gets a
404 not found error.
Thanks TOBY
