I've just had a brief look at this, and I must congratulate those 
responsible for implementing this system. I just have a few questions and 
comments about it.

Firstly, are there any plans to replace the various mirrors on archie.au 
with (perhaps) links to the original archives? Also, is there any way to 
actively redirect overseas FTP requests to archie's alex filing system? Is 
this not a good idea? I suspect that the caches would work better with more 
traffic, up to a certain limit of course.

The impression I get (note, no figures) is that FTP accounts for the vast 
bulk of traffic on the US link, right? If so, then surely an active 
redirection scheme, if possible, would vastly cut this? Of course, the 
traffic is still really there, but the caching should reduce it 
significantly...

Finally, one "feature" I noticed was that the files I looked at were dated 
1st Jan 1970, what one might call a rather "suspicious" date <grin>.

BTW: All the comments above are on the assumption that the system 
eventually moves out of the testing phase...
