Microsoft Data Center in Des Moines, Iowa DDOS

Question

So I'm seeing thousands of IP's originating from the Microsoft Data Center in Des Moines, Iowa in attempts at scanning or DDOS.

Just some of the IP's I have seen are listed below. Have listed the low and high range of each subnet I have seen, eg 13.67.144.20 - 13.67.144.189.

I have also submitted a report via https://msrc.microsoft.com/report/abuse (Microsoft CERT Report SIR12550748) however that form allows one to only list one IP at a time.
