Over the past 24 hours Xbox One units all over the world were affected by a widespread outage that caused the friend list not to be displayed and all related features to be unavailable.
The Xbox team has been at work on the issue for the whole time, while some users reported intermittent access to the friend list and others were completely unable to display it on their console.
Luckily, the problem has finally been fixed, and Xbox friend list is finally available again.
If you were affected by the issue, and you’re still unable to see your friend list, a full power cycle for Xbox One and for Xbox 360 users may need to clear cache. This should solve the problem, and you won’t be lonely anymore.
