Well, that is usually solvable quite good with a primary site that only
allows other mirrors to connect. After those 10-20 mirrors or so have
managed to get the images, there are usually enough bandwidth around for
the other mirrors to update resonably fast.
Sure, the servers (especially those that updates first) are going to be
slow for a day or two, but I'm pretty optimistic given the master server
is pretty much unaffected by the release.
