I don't bother about such problem because I have my account at Twitter as well and I'll concentrate on it if Facebook is down.
Been down a while now, 30 minutes I've been checking and for the second biggest site in the world that's a long time! The amount of lost revenue just for being down 30 minutes will be HUGE!
Still down... Noticed a few hours ago and still not back... I wonder how many third-party sites are affected that work with Facebook Connect and FBML??????????? Millions????????????
This is a very old thread but Facebook is rarely down, perhaps never, but it is perpetually innaccessible due to its server load and excessive scripting nuisances. Everyday is the same pain, get it loading and loading and loading until you finally get there, but only to crash your browser with the game applications. At least I have this behavior on a daily basis :\
