Despite it never happening to me in few years of using AWS, Ill explain the difference between this example and mine.
Payment example shows the issue on your end. Something you have control of. In Azure example, companies could do nothing to prevent that outage. Sure you can run services in multiple regions but then you pay absurd amount of money to transfer data between regions (at least in case of AWS).
If I'm not mistaken, in Azure's case the issue was with some authentication service that was hosted in only one region but was used by all of them. The service had no redundancy.
