Xbox live core services down (Don't do what I did 2018 05 20
Xbox Live Core Service Outage on Xbox One, Xbox 360, Windows 10 and other Windows devices. Don't do what I did and reset your console! I didn't see this service outage up yet on the Microsoft support page when I checked after not being able to sign in so I reset my console to factory condition. After it was finished resetting I checked the website again and the status changed to being down. Oops
