Hmmm, I'm pretty sure a majority of our traffic is currently
from North America.

Now, from a performance point of view, this isn't a very big
problem. Quick test revealed sunstained FTP transfer rates
of:

 ftp.gnome.org        530 kb/sec  (No anonftp users, 5 miles down the road, 8 hops)
 ftp.kernel.org       330 kb/sec
 ftp.umu.acc.se       230 kb/sec
 ftp.redhat.com      ~100 kb/sec  (no this isn't on my local network)
 ftp.sourceforge.net ~100 kb/sec

So, quite decent transfer rates from North America. 

But from a good-network-citizen point of view, if most of our traffic
is from North America, it seems that we probably should try to have
ftp.gnome.org in North America.

I think the first thing we need to do is to make sure all 
interested mirrors have the current rsync password and are rsyncing,
and we have their contact addresses.

Then we'll be better in a better position to evaluate

 - How much spare bandwidth we have at the main gnome.org site
 - Whether there are interested mirrors in North America with
   comparable connectivity.

But certainly we appreciate the offer, and probably should
at least make umu.acc.se ftp.eu.gnome.org.

Regards,
                                        Owen
