From the Official AO Forums:
\"We are currently building and deploying the client updates ready for download. We expect that we will be in a position to open up the servers in around an hour and a half. Apologies for the additional downtime we are just ensuring that all download options are available and working.
So the current ETA will be around 0330 CET
