I've experienced this problem for TWO YEARS because I thought it was somehow related to my ISP, but now that I've moved to a completely different state and ISP I know that it can't be. For some reason, a VERY few number of sites won't connect for me and just time out and "fail." Nothing wrong with the site so I don't understand it. The main site I have this problem with is Twitter.com. If I go behind a VPN like Hotspot Shield, no problems and it's zippy. But without connecting to Hotspot Shield, it won't connect to the website. I have this problem with two other non-mainstream websites I visit. I encounter the same problem with the same websites on WiFi with my iPad and iPhone so I'm thinking it has to be something with my Airport Extreme and its settings. Does ANYONE have ANY idea what is going on here?
