It's most likely a problem with your location on the 'Net, and the route your packets take. For instance, I've never had any issues with accessing daemon forums, and my route is nothing like yours:
Code:
$ tcptraceroute www.daemonforums.org 80
Selected device ath0, address 172.20.0.5, port 55996 for outgoing packets

What does your traceroute look like when you can connect?
