Interesting mirror rediness results for alpha

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:

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:

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.
