When is there scheduled downtime/weekly maintenance?

Other MMOs I've played in the past (Star Wars Galaxies, EverQuest 2, World of Warcraft) had a specific time each week that they took their servers down for maintenance.

Does SWTOR have weekly scheduled maintenance periods?


Yes, although it appears to be more of a rough schedule:

Generally speaking we are aiming to limit our scheduled maintenance period to once a week, on Tuesdays. We are aiming for this weekly maintenance period to take place in an off-peak time for both North American and European players. We are also aiming to inform players of the precise duration of any weekly maintenance period at least 24 hours before the maintenance begins.

3AM EST is the normal maintenance time, so the European servers go down at 8AM GMT and so on.
