Today, December 11, 2009, is the VERY FIRST time I have been able to access FlyerTalk since November 17, 2009, and it wasn't for a lack of trying.
All I have ever gotten in between these dates was a blank page (on Firefox) or a page explaining that the website is down (on Google Chrome).
Incidentally, I am accessing FlyerTalk for free on GoGo Inflight Internet on a Delta flight from CVG to SFO. Maybe you have to be 40K feet up in the air to access FlyerTalk!
By the way, GoGo is offering free internet through 12/31/09 if you use the promotion code DELTATRYGOGO. The regular price was $9.95.
