That's when everything is working right.

If all of the mirror sites are basically independent, there's no way
to know for sure that all of the mirror sites are working properly,
one of them may even be several days behind, for whatever reason (like
broken networks isolating it from freefall).

I would prefer to know that when I run cvsup, I'm going to get a newer
version of the FreeBSD repository, not an older one.  When using a
specific mirror, something has to get *really* screwed up for that to
happen.  Of course I don't use any of the US mirrors myself, anyhow,
but I suspect that losing changes may cause unexpected problems.  Use
your imagination.  ;--)

At the very least, problems with one mirror could cause significant
increases in traffic on all mirrors.
