Can't Login

I've been trying to connect to the Lordaeron WotLK server for the past day. The "connecting" box displays and after a short time an "Unable to connect. Please try again later" dialogue box appears. This issue has only just occurred, as I have been able to login in the past. In my LOGS folder, the connection.log text file shows the following after my most recent connection attempt.

12/6 10:38:23.627 GRUNT: state: LOGIN_STATE_CONNECTING result: LOGIN_OK
12/6 10:38:44.693 GRUNT: state: LOGIN_STATE_FAILED result: LOGIN_SERVER_DOWN
12/6 10:38:44.721 GRUNT: state: LOGIN_STATE_FAILED result: LOGIN_FAILED

Thanks for any assistance, and many thanks for what is usually a great gaming experience.
