they probably do. I worked for a content-as-a-service company that had a contract to deliver our product, airgapped, to a three-letter agency on a regular schedule, and we were a tiny company. Microsoft’s biggest customer is probably the U.S. government; I’d be shocked if they don’t provide an in-house airgapped set of full Azure services for the entire intelligence agency system.
aaaaargh I wish I could draw.
