Well for some reason iam getting an error message saying that my account is unavailable, could it be that facebook is implanting timeline to all members ?
I get the same error when I try to log into your account too. No, seriously though, it's related to SOME accounts using the timeline thing, yes. It should be back soon. Been happening frequently to lots of my clients.
I am using timeline, and facebook opens fine with me.
Try updating your browser, or delete all the cache.
Facebook is buggy, has always been - I wouldnt get too worried.
As rolf said, Facebook is being very buggy lately. They have a problem with their server. You may also notice delay between notifications and sometimes delay between comments.
I ended up using hotspot shield, and my problems were gone--stupid dns problems from Ogero which appear from time to time (at least for me).
