I got as far as it saying that once, now it just tells me my username and/or password is incorrect.
The one time I did get in with the servers down error, I tried to launch BF3 for some campaign action and it just failed, didn't even try load up battlelog, just straight to black screen and had to manually kill it.
The razor origin bypass fix is looking more tempting by the second.
Edit: I'm in, god only knows what on earth EA have managed to do, but I reset my password at EA's website, to exactly the same as the password was before, and it logged me in straight away.
