Seeing the 3 hours of downtime and full system failure so far, I already view this as a serious outage with widespread and costly effects, where machine spindles are going silent.

The Autodesk cloud services seem to be made with next to no offline functionality and next to no offline backup. Without great uptime for the services, we are just going to need to go back to buying Mastercam and SolidWorks licences that can be run offline, or their equivalents.
