Hey Bill --

I recently noticed extremely slow download speeds from http://opensource.apple.com/ -- looks like it's on the same network as distfiles.macports.org.

For what it's worth, here's my traceroute from my local machine:

On another machine in SF, I have perfectly reasonable connectivity, no slow down. This is the traceroute from that machine:
