DNS


Yeah, I wondered about that when I first ran into this, and it's what my brother suggested might be the problem, as well. However, that wouldn't account for why I can ping the server in question using its canonical host name, and get a reply back, but get no reply with http.

If it's a problem with the MTU, as suggested, that makes more sense, since (I'm guessing) the ICMP packets are tiny, whereas the HTTP packets in question are much bigger, and get stuck.
