I haven't managed to read all the mails in this thread, however, I have one
or two thoughts:

- The splitting out of parts of the tree, so that primary servers do not
	need to carry everything that is on ftp-master is probably a good
	idea - the archive is growing to the size that is not justified
	by the volume of downloads that it generates.

- Some thought should be taken towards ensuring that there is at least
	one primary mirror in each geographic region (probably on each
	continent). -- It is enough of a problem with the delays in
	syning, due to the high latency all the way from ftp-master.
	(Remember that in South Africa, we are dealing with at least
	250ms, or more - up to 600ms - RTT to ftp-master, which seems
	to affect cvsup quite adversely.  By having at least one
	primary mirror in country, that allows other mirrors in the
	country to get the bits quicker.

My second comment must be seen in the light of the first.

Regards,
Geoff.
