Having something more like CPAN would be preferable because its mirrored on over 400 sites across the world (http://mirrors.cpan.org/ http://mirrors.cpan.org/)

Having something more like CPAN would be preferable because its mirrored on over 400 sites across the world (http://mirrors.cpan.org/ http://mirrors.cpan.org/) and should any CPAN author decide to delete any of their modules/distros then it is still accessible via BackPAN (http://backpan.perl.org/ http://backpan.perl.org/). I suppose this is one of the great advantages of CPAN being developed in the era of modem based internet :)
