Were you able to ping or traceroute the site when you booted to the Mac OS X install disk? That will isolate the issue to your computer or your network/isp. I know you said it happens from multiple locations but there could be a common node causing the issue, like if you MAC address is ghosted out there in internet land.
You haven't isolated the issue, so doing troubleshooting is kinda pointless since you don't know where you're looking.
If you do end up isolating the issue to your Mac, then try both AirPort and ethernet, test in a new user, and try making a new location in Network Preferences. Depending on where it works and doesn't work helps you isolate the issue so you know what you're looking for. Otherwise you're just doing shotgun troubleshooting.
