The difference I see is that AWS didn't seem to have suffered a non-region specific service outage yet. Whether or not it's related to the South Central US region outage, today Azure Active Directory was down for ~4h. Because it's not running in a particular region, no HA or DR strategy, other than having your services be deployed to multiple cloud providers, would have mitigated the outage.
