Well, when I first set up a CPAN mirror, the docs strongly suggested
using another mirror as your source.  However, after having trouble
staying synced, a mirror I synced from closing down, etc., I gave up and
switched to syncing to the master anyway.  Due to that past experience,
I have not put much effort into Fedora mirror tiering.

Running a mirror is something I do in my spare time; I don't need
requirements that make it take more time to manage.  Right now, it is up
to individual mirrors to find a higher tier mirror, get private access,
etc.  If you want it to be widespread, it must be easier.

High-tier mirrors should be required to use mirrormanager-provided ACLs;
mirror operators should not need to contact individual high-tier mirrors
to set up ACLs.  High-tier mirrors should be very tightly monitored and
must be synched as soon as possible after updates (with published
schedules if possible).  With the high churn rate of rawhide, tight
synchronization is a must.  I don't want to have to continually monitor
whether I'm in sync with both a high-tier and the masters, switching to
another high-tier or master mirror at the first sign of trouble.

What I DON'T want to use is any kind of DNS alias that can point to
multiple mirrors.  We've seen how much "fun" that can be just with the
download.f.r.c masters (which presumably are tightly controlled and
monitored).

I don't think rsync supports any kind of redirect, does it; that could
make this easier (lower-tier mirrors could be automatically redirected
to a preferred high-tier mirror, with that redirect only changing when
there is a problem with the high-tier).

I don't speak for anybody but myself - that's enough trouble.
