Quote from BioWareHello everyone, we wanted to let you know that we will be performing scheduled maintenance for six hours on Tuesday, July 10th, 2012 from 2AM CST (12AM PST/3AM EST/8AM GMT/9AM CET/5PM AEST) until 8AM CST (6AM PST/9AM EST/2PM GMT/3PM CET/11PM AEST). All game servers and SWTOR.com will be offline during this period. This maintenance is expected to take no more than six hours, but could be extended.
If and when a patch comes up along with the servers, we'll have the patch notes available here. For the original post in its entirety, visit the official thread.
