Moments ago, BioWare announced that Game Update 1.4: Terror From Beyond is on its way to release early tomorrow morning. Along with the announcement came a new scheduled maintenance post that replaces the postponement of Tuesday's regular window.
Quote from BioWare
Hello everyone, we wanted to let you know that we will be performing scheduled maintenance for six hours on Wednesday, September 26th, 2012 from 2AM CDT (12AM PDT/3AM EDT/8AM BST/9AM CEST/5PM AEST) until 8AM CDT (6AM PDT/9AM EDT/2PM BST/3PM CEST/11PM AEST). All game servers will be offline during this period. This maintenance is expected to take no more than six hours, but could be extended.
Travel to the Gree controlled planet of Asation, where you’ll join others in an intense series of battles leading up to a final face-off against an unyielding enemy. It’s up to your team to close the Ancient Hypergate, opened by the deadly and malicious Dread Masters, and destroy a galactic goliath before it destroys the galaxy! Learn more about Game Update 1.4 here!
After this maintenance is over, restart the game launcher to patch to Game Update 1.4.
