An alternative solution is:

sudo echo 'net.ipv4.tcp_window_scaling=0' >> /etc/sysctl.conf

It seems to be mostly isolated to Linux, and because I use a non-Windows/non-Mac machine, the person at OIT refused to help me or even acknowledge that there could be anything wrong with the site. Another friend, who also uses Linux, encountered the same problem.

My network settings seem ok, and I'm able to load just about any other page with "osu.edu" or "ohio-state.edu" strings in the URL with no difficulty whatsoever.

Has anyone else experienced this issue or have any advice? I really don't want to have to separately boot another OS whenever I want to see my financial aide statement. For anyone who asks, I'm using Firefox, and Ubuntu 7.04. Standard DHCP network configuration, with no proxies or anything. I'm also curious if it's only Ubuntu (which would mean it's an OS problem) or other Linux flavors (meaning it's a server problem).
