Usually no but they're probably getting swamped with requests right now. I get that login attempt error as well. I found that typing the password really slow works. Who knows why but it does.
For the "you're already logged in error" sometimes deleting cookies, shutting off your computer and trying to login in after a few hours works. If you try logging in right away you'll just keep getting the error.
I'm sure you've already tried all this but good luck.
