I'm scared that it's not a big deal because they haven't said ANYTHING about it.

Probably something minor to prepare for the big update tomorrow if there is indeed one.

Why would they do that? Lol, that doesn't make sense. The maintenance, if anything, would have been to prepare for the update.

Come on, GAF! Homework can wait, this shit is important!
