The ops team is currently distributing a client patch to the servers, which could take up to 30 minutes. I apologize for the inaccuracy of the last announcement, as the required client update added to the ETA.
If you are logged in to the game, please log back out. I'll post an announcement when the game is open for play again, at which time you can log on and get the updated client.
We're sorry for the continued delay and will have the game back in service as soon as the client update has been delivered.
