It was working fine for me until the minute I hit Upload on a video. I was entirely convinced I'd had my account auto-banned or something, and was very confused/frustrated. Couldn't find any mention of it anywhere at that point, then this thread popped up. It's pretty telling that YouTube is so reliable, and Google is so horrible to their users, that my first instinct was that I got banned for no reason by some bot, rather than the site was broken.
