That's sure a long list of distributions etc. that they mirror, but the site was a bit unresponsive.
I noticed CPAN as the first item in the list. What an amazing resource it is for Perl users. I've used it a fair amount and am amazed by what's available.
My favourite mirror, which has less stuff, but has very friendly, and quick, browsing is:

http://mirrors.vbi.vt.eduI use one or t'other to keep my Slackware up-to-date, so no need to experiment with other distributions
