this sounds interesting... would there be interest to also feed these
results to a dns server, so that mirrors.fedora.<something> is a
rotating dns between all "validated" mirrors? (this assumes the same
location of the files on all these mirrors obviously)
it also generates country-specific files - and I've generally found
relying on dns servers to honor TTLs all over the world is a bad idea.
dns probably scales better than a cgi ....
not if you have to use the ip to respond with a proper list for that
country, or, failing the existence of that country's list - respond with
the global one.
I've found the relying on dns for anything frequently updating is just
asking for agonizing caching issues you can do nothing about and
irritated users.
