A while ago I hacked together a "name and shame" list for the Ubuntu,
Fedora, and Debian mirrors :)

The Ubuntu list has a nice layout and is grouped by country, so this
makes for interesting information. For example, the majority of the
French mirrors has IPv6. And half of the Dutch ones don't have IPv6...
even worse, two of them are SURFnet-connected universities... so it's
not like they can't get the connectivity or something.

I've banged on their door as well, for instance to fix
(, but
that's almost two years ago and nothing happened :(

Let's hope someone from Canonical is on this list and is able to push
the right buttons...
