The mirror choice algorithm is far more complicated than round-robin
by geo-IP.  Of course, it isn't perfect, but is a decent
approximation most of the time.

Patches or enhancement bugs filed suggesting ways in which the tools
you're interested would be more verbose are welcome.

This, my friend, is just a pot shot.  We're _lucky_ to have so many
mirrors, and in most cases, mirrors with very responsive
administrators; not to mention the Infrastructure team that keeps it
all humming.  If you have genuine problems with particular mirrors,
feel free to let the folks in #fedora-admin know, or file a ticket in
the Fedora Infrastructure trac
(https://fedorahosted.org/fedora-infrastructure) with the details.

Thanks,
Matt
Fedora Mirror Wrangler, and proud of it! :-)
