Debian uses DNS tricks to distribute mirror load.  It proved to be
necessary because we can't be too picky about mirror offers, and the
network operators tend to be not very upfront about choke points.  A
solution based on redirects would likely confuse unofficial mirrors.
(Our own client doesn't support them, but that could be fixed.)
