Can you do some tests from your network to theirs and see if there is a
bottleneck somewhere enroute ?

I can fairly easily plumb in a scheduled regular tests that would check
b/w rates from various places. However, the question then would be :
what is a reasonable acceptable[1] performance test.
If we can come up with a test that is considered acceptable, we can then
move to adding a metric from there into the mirrorlist generation to
make sure that slower mirrors are used more infrequently.
The caveat here being that even through a machine might only be 10mbps,
because its used more infrequently - it might give its 2 simultaneous
users a better / faster experience than the 100mbps machine can to its
500 simultaneous users.
Thoughts ?

[1]: acceptable to the mirror admins. I dont think they would like it
much if we were to pull a 600M iso every 6 hours as a speed test.
