The forums got lots better last night (you probably noticed they got more responsive). That was us patching them to fix Internal Server Error issue. The forums should be fast right now. The only downside is that you'll notice about a 1 minute delay for updates to occur to the forum listings. We're going to reduce that delay as soon as we know how much we can lower that "cache" time. There is one other major issue regarding "Service Unavailable" messages, but other than that, from here on out you should notice the forums being much better than they were before.
