The regularly scheduled maintenance periods for Star Wars Galaxies occur on Tuesdays, Thursdays and Saturdays from 4am – 10am (Pacific Time). Please note that although these are the designated ‘downtimes’ (and players should not be surprised if they can’t access the servers), it is also possible that some maintenance periods may conclude prior to the end time or even extend beyond it. We will convey additional downtimes to the best of our ability but keep in mind that maintenance periods are always subject to change.
