What about right now?
Getting too many log in attempts?
I'm afraid that's likely a result of...
Our game worlds were subjected to a sustained attack. We've had to temporarily add some restrictions when logging into the game or world-hopping repeatedly to help mitigate such attacks. If you're unable to login to the game as a result of these restrictions we recommend waiting a short period of time before trying again.
I appreciate that this isn't the most helpful advice - and it might prove frustrating even (and I apologise) - I can only suggest allowing a period of time before attempting to login again.
