Well clearly we have incontrovertible evidence now (if it was needed) that YOLO-pushing insufficiently tested updates to everyone at once does not work either.

This is being called in many places (righfully) the largest IT outage in history. How many billions will be the cost? How many people died?

So yes, clearly not the correct way to operate.
