In response to the why a week later, the bottlenecking was a joke when 4.2 released followed by emergency maintainance. This was just for new content and the raid. It would have been 100 times worse had housing also been unlocked at the same time and impacted other people not interested in housing.

Regardless had it launched at 4.2 you would have still had exactly the same issue. Maintaince always happens before they add and it always ends around the same time. They operate off of Jpn working hours and NA drew the
Short straw due to time zones. Nothing more to it than that.

And as for the 1 hour thing. Seems like an oversight that it is not on the lodestone, but it's was directly from Yoshi himself in the Live letter. I watched it. Go back and watch it yourself if you need the proof.
