Yep, I just experienced it as well, a few times during the build up to the 17:00 at Brighton. In fact I've just reloaded BA and it's still b0rked. I managed to get out of my trade in between the outages.
I'm completely down as well, I just logged in to the BF site and it says my wallet has £0.00 in it (eeek!). Tried to access my account page and that comes back with 'Http/1.1 Service Unavailable'.
