I feel like posting the traffic output of the network might not be a great idea because they might do these attacks on purpose to market their network's capability.

Why wouldn't microsoft advertise this though? If they had the ability to take the attack and others might not, then it'll result in more customers for them.

it's an open secret at that point and the attacks are far larger than that are causing congestion world-wide from the time they wake up to the time they go to sleep.
