So, I've been monitoring the mirrors all day, its been sort of a manual process (thus the sporadic times there). I'm going to re-run this for the beta and continue to run it for the alpha but the results are not at all what I expected:
http://mmcgrath.fedorapeople.org/alphaMirrorRediness.html
So the 10:00 AM portion is when we announced the alpha. People coming to the mirrors would have had a less then 10% hit rate. It went up from there mostly and wasn't until hours later that we saw a big spike upwards (after a mirror crawl completed).
What I don't understand is why we've actually started losing mirrors. We were almost at 90% hit rate for a bit today, and now we're back down to just above 60. Any theories? I'm going to keep monitoring. Feel free to monitor yourself. I've basically been going to:
http://download.fedoraproject.org/pub/fedora/linux/releases/test/11-Alpha/Fe...
And seeing if it comes up with a found or not found/perm denied. I'm going to think on my methods a bit. Currently I'm just running wget's in a loop for 5+ minutes at a time and taking the total number of 200's / total requests * 100.

That one is easy. As mirrors get swarmed by users, they start refusing connections or just timing out.

Ehh, The trick there is I don't think they're actually getting swarmed. None of my tests have been timing out or refusing connections, mostly 403's and some 404's. It could be mirrors refusing through a 403 but from what I've seen, the mirrors throwing a 403, throw a 200 OK for the F10 release.
