The black screen problem had some fans worried that their systems broke, as you can see on the Xbox One Reddit page. The Xbox Live status page lists core services as “limited” on Xbox One.
Typically, problems with Xbox Live just result in people being unable to log into their account. Seeing a black screen when booting up the console is a more severe problem.
