We have been recommending that people _not_ use download.f.r.c
directly, but instead use one of the download[1345].f.r.c hostnames
explicitly instead (yes, download2 doesn't exist).  This stems from
the days when we had master mirrors in multiple locations, and
download.f.r.c would round-robin between masters at the different
sites, sometimes with them not quite in sync, which was problematic.

At present download[1345] all use the same back-end file system, so
they are equivalent.  In the new location, a similar setup will be
available, with 1 netapp data store, shared to 4 separate rsync
servers, served via one public IP address and DNS name
download.fedora.redhat.com on a load balancer.  The download[12345]
names will simply CNAME to the download.f.r.c name and its single new
IP.

So, if you're using the names like we've suggested, there should be no
change for you.

Thanks,
Matt
