Mirror Download sites

[norm]

Apart from investigating each site it is in some cases a challenge to
find the nearest download site.  If the site has the name of a
university in the address it is relatively easy to determine the
general area of the server but for sites with other names it is more of
a challenge to determine the location.  Probably the quickest and
simplest way to determine the mirror site closest is if there was a map
indicating the approximate locations.  Has anyone gone to the trouble
of creating such a map or a form with the web address and the city  the
server is located in.
