I think they're on schedule. It's Tuesday evening here, which has been always the time on my timezone (specifically 7-8 PM on GMT+8) when a new event goes live. What I did not notice though is... did the devs ever post some sort of an announcement on the black marquee bar? 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.
