21:05 UPDATE : the system has now been restored and there should be no more problems. ORIGINAL REPORTING: If the last time you tried to power up your Xbox One (regardless of type) and have been greeted by a plain black screen and a panel locked, don't worry, it's not hurt : there seem to be unprecedented and unusual problems that cause this behavior on the Live, of which Microsoft is aware and whose resolution is working actively.

The only workaround at the moment to avoid the problem is to turn it on when you are offline, although you may not be able to reach the network options screen; so if is connected with cable unplug it, and if it is in wi-fi you can try to turn off the router and then turn it on. We advise you to keep an eye on the Xbox support Twitter to get updates on the problem.
