Zephyer you are confusing battle.net and battle.net 2.0 world of warcraft has always had maintenance and patches on Tuesdays, and when starcraft 2 came out, and wow and starcraft 2 were partly joined through battle.net 2.0 blizzard started having patch/maintenance days for BOTH on Tuesdays.
If you play starcraft 2 it should be no surprise. they've done it since launch.
