Where to still find a Debian 4.0 (etch) ISO?
I went through the mirrors list for the latest release and found this mirror:
http://mirror.aarnet.edu.au/pub/debian-cd/http://ftp.riken.go.jp/Linux/debian/debian-cdimage/archive/
They still have 4 available. This was the second mirror on the list so I imagine some of the other ones have it too.
Both of the mirrors are down as of today.
