Overall, it doesn’t matter who’s fault it is. We paid MS for a service. They’re failing to deliver said service in a reliable manner. Whether it’s their hardware causing issues or stability issues with Asobo’s services running on said hardware (I would suspect the latter), the end result is the same. And this is a Microsoft product, not an Asobo product. MS are ultimately responsible.
Only Asobo are the ones that maintain the services and are the ones with the finger on the switch to cycle these services and get them running. But it’s a long weekend. And unless you’re in the service industry or emergency services, pretty much no one works in France on weekends or holidays.
We may get lucky and someone will reset it before Tuesday morning, but I wouldn’t hold my breath.
