In this case, I would let the country's hostmaster verify the
sites and decide which ftp sites are tier 1. The only effective
change would be to add ftp1.XX to the sysisntall site list. If the
hostmaster decides not to use round robin, just point ftp.XX to
ftp1.XX or anyone else. Note that I did not say that every site in
the country would be automatically added to ftp.XX.FreeBSD.org.
And the definition of "close tier 1" would be easier with the
proximity algoritm I described earlier. How many FreeBSD users really
know which site is closer to them? How to check this before
installing FreeBSD? I know how to, but definitely, most users don't.
