I was on the game, albeit idle, until the last 5 minutes before this downtime and still kept seeing the Black Baccara step-up news.

Not that I noticed, I went for lunch, came back, and got the maintenance screen.
According to the in-game event banner (the ones for phase one and phase two on the mission screen), the event was supposed to last another 15 hours though.
