Debian stuff
Geomirror
An implementation of automatic mirror discovery based on DNS and geolocation is currently being tested and slowly developed. It can be used simply by replacing whatever mirror host you’re using in /etc/apt/sources.list with “$(ARCH)-geomirror.debian.net“.
It was implemented as a small script that works as a backend to PowerDNS’ Pipe backend. It reads information from the Debian mirrors list and selects the appropriate mirror based on geographic location, using libgeo-ip-perl, and some simple heuristics.
The code can be found in the git repository.
