wow! you have access to the response codes received by most of the clients
countrywide? and i thought i had to be running webalizer or something on
the server end to do this ... :-)

ftp.iitm.ac.in is a heavily used mirror and there is no other such service
(yet) anywhere else in india. however, we do have only finite bandwidth
and i have to put some limits on usage so the resource is meaningful. for
example, there is a bandwidth cap and there is also a connection limit,
currently 10-20 mbps (depending on network usage by other users on campus)  
and 100 connections. we are running at or near the connection limit most
of the time, so lots of users will get 503 messages. we are recording
about 10 million hits a month and about half of these are getting 503's.
if i increase the connection limit, sure, we will get fewer 503's, but
download speeds will go down for all users - to below dialup speed. if 
there is collective wisdom that this is preferable, i will consider 
changing this.
