Update from Microsoft
"We have identified that calls made during service management operations are failing due to a required artifact version not returning as expected during query. The failure shows that that a required extension cannot be located. We are currently implementing a mitigation option to force a refresh of the extension and are seeing signs of recovery where mitigation has been deployed. We expect recovery to be observed as the mitigation progresses across regions."
We (CloudM) will continue to monitor the situation and update you periodically (every 3 hours) or as events warrant.
