Sorry about that.
When we updated the forum, we installed it in a nice new server environment. It's been working great for general performance and tested really well when we brought it online.
Recently though some of the new security features that help keep the forum running so smoothly started to show some snowball-effect problems that took a while to gradually build up and cause trouble.
It took a little bit of analysis to see exactly what was bringing her down but I'm happy to say, I think I've got it ironed out now!
