I would be interested in hearing details of the FTP archive servers
being run at Switzerland/Denmark/Finland.  How many gigabytes?
How many files requested per month?  What is the average size of
a file requested?  Which file is requested most often?  What
percentage is local requests?  What percentage is European
requests?  What percentage is non-European requests?  Which
systems do you mirror files for?

You get the general idea.

Thanks,
Hank
