I'll look into this over the summer.

They are hitting the same server, but that server is portsnap2 (which is
also portsnap.daemonology.net, which is the default server for pre-1.0
versions of portsnap from the ports tree).  Given that most systems running
portsnap are FreeBSD 6.0 or 6.1, this doesn't cause much differential
loading.
