Yeah, my theory is that it's just about 2 weeks after everyone is back from holidays, which means all the engineers are back and ready to ship features and changes after nothing's been touched during the holidays. All this "go fever" is leading to somewhat reckless modifications of production systems.

FaceTime (a little bit different case though) 2 days ago, GMail yesterday, and Office 365 today.

Came here to make the same observation. Good on teams at Microsoft to not allow themselves to make a "we're more reliable than G Suite" joke.

Or not funny. Suspicious coincidence. Hope it is just that and not outside actors testing things.
