At the moment, the system works by selecting the best closest mirrors to
the IP, checked out by GeoIP lookup to the country level, and hands them
out - they are randomised to get a good spread across all mirrors (eg.
in the US we have over a 100 mirrors, and we want to try and get as many
of them traffic as possible ).
Almost all mirrorlist calls should return mirrors in the country ( if we
have some there ) and some from nearby ( geo ) countries.
FastestMirror will do a socket connect to each of those machines and
order by speed of connection, it isnt foolproof but the results are
usually 200% to 250% better than the unordered list.
