I changed the DNS to bypass the load balancer for now until we figure out what the hell is going on. Right now all traffic should point to 67.159.47.218.
i was having the same issues as mentioned above with the blank pages (vista 64 firefox 3.5.5) but i switched from my custom number of posts per page (75 or 100 i honestly don't remember) to the forum standard of 25 the problem seemed to disappear
