If you're running into issues with Xbox Live right now, you're not alone. According to Microsoft's Xbox Live service status page, some users are impacted by outages with the Xbox social and gaming services. The main issue appears to be related to viewing achievements, your friends list, or the activity of friends.
From Microsoft:
Our engineers and developers are actively continuing to work to resolve the problem(s) that is/are causing some members issues viewing Achievements, Friends List or the activity of friends. Stay tuned, and thanks for your patience.
It looks as though issues first started cropping up on April 1, and a number of Reddit users have reported various issues related to viewing gamerscore and getting kicked from online matches. According to Microsoft's status page, in-game matchmaking, cloud storage, finding friends, Game DVR, leaderboards, avatar editing, or pictures may all be affected.
If you're impacted, Microsoft is working on the issue and should have it resolved before too long. For now, you can keep an eye on the Xbox Live status page to keep track of any progress.
