It's working for me today. Maybe squeaky wheels get grease.
Anyways, I have a theory to offer, which is that this isn't a "DDoS" as is being reported. I've heard an unsubstantiated rumor that recently a security vulnerability has been attempted to be exploited in the vBulletan software, and that the "CloudFlare" thing is intended not to defend the forum against a DDoS, but instead is intended to slow down a brute force attack. I haven't the time to research this, as I have other things to do, but perhaps maybe someone else can run a few Google searches and report if there is anything to this.
