Same happens to me. Happens almost every time I click on a thread, or a forum category, or anything. It does not appear to happen on non-forum pages on flyertalk.com. Loads the thread for a split second, then gives "The page was reset." Sometimes takes a refresh, sometimes 2, sometimes 5. Interestingly, I am also on RCN though in a different geographical area (SE PA.) It happens in both Firefox and IE8, and happens whether or not I am logged in. It does not appear to happen if I utilize a proxy service, though of course loading is very slow. I have not seen this behavior on any other website, including 5-6 other forums I read. An extended ping test indicates only 7 lost packets in 1000, effectively 0%. Repeated tracert tests had no missed hops and no hops with gratuitously long delay.
