My money is on expired domain somewhere or security certificate.
MS engineers are waiting for an online purchase of a new $400 keyboard with the Copilot key to complete and planning to run to the data center to plug the keyboard.
However, the Bing outage is preventing the purchase to go through, because the payment somehow relies on Bing suggestions to load for obscure reasons.
I also appreciate that you prevented me from countering using a guard like "if RDP is enabled and working", and that a follow up answer actually provides the missing piece xD.
