This is not my problem, here one machine can cope happily with
the 600 user, of which only a few tens are "power users".
Main concern was to be able to shut down the machine for a
certain time, and being sure to have all the stuff arrived in the
meantime redy.
The only drawback is that if the problem in in the line that connect
our site a connection from external have to try two "disconnected"
hosts before trying on the third or the fourth one .
