And if one was to read the posts about the maintenance you would know that these maintenance times are an exception, not the rule and Bioware is looking to implement a set routine that has maintenance outside peak play times.
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.
The upcoming maintenance windows (detailed below) are exceptions, and are needed to prepare ourselves for our official launch on December 20th.
