As part of giving back to the community LCHost runs a Debian package mirror (including backports) (for i386 and amd64) which was recently added to the official mirrors list.
I spent a little time making it automatically detect changes at our source mirror within a couple of minutes and pull down, so at most it’ll never be more than 5 minutes behind the top-level mirrors.
To use our debian mirror, simply replace your regular mirror definition in /etc/apt/sources.list with:
deb http://mirror.lchost.net/debian/ stable main contrib deb-src http://mirror.lchost.net/debian/ stable main contrib
(You may choose to use the release name in place of “stable” to ensure you never accidentally go between major releases – so for wheezy, simply replace the word stable with wheezy)
If you use backports, you can get those packages from us too, using something like:
deb http://mirror.lchost.net/debian/ wheezy-backports main
