Maintenance is almost always right before the weekly reset. This is nothing new. In fact, you should have expected if there were maintenance for a new patch that it would be at the exact time that it is scheduled. SE keeps things pretty consistent, they aren't going to coordinate maintenance based on whether or not someone might have been busy all week and didn't get a chance to play.

Your complaint is like those people who wait to go Christmas shopping until Christmas Eve and then get mad when the store closes early and they couldn't get what they wanted.
