There is no scheduled maintenance this week, but the Gree Event returns tomorrow! You can read more about that here.
The next patch will be Game Update 2.1.1, and it's scheduled for next Wednesday, May 29th. The reason we're not doing maintenance on Tuesday as normal is because Monday is a holiday in the United States.
Have fun out there!
Thank you for the quick reply. However I am pretty sure you just posted an internal Bioware link instead of something we can access
