While not all users are experiencing it, a portion of Xbox Live users are currently experiencing issues with connecting to the service. It’s not your connection, as Microsoft and the Xbox Live team are currently investigating the issue.
No official cause has been identified and the Xbox Live team has not announced a timetable for a potential fix. They have, however, stated that they are working to resolve the issue. We would expect the issue to be resolved within the day, if not within a few hours.
