I believe that if more and more people join and stay on at the same time, then we might be getting that "page unavilable" thing more often then we do, usually it has happened to me only twice (the release of the Red band trailer, and the five minute intro) the average amount of people i see is 50-70, usually for me the problem occurs at 120+. Just saying that this problem might occure far more times if the average amount of users online will be 120+ rather than 50-70.
