UPDATE 11/6: Full Xbox Live services have been restored as of 11:00pm CT. Original story follows.
Earlier this evening, Xbox Live services went down for some users, making it impossible for some to access their digitally downloaded games across Xbox One and Xbox 360. Xbox Support tweeted about the incident, stating that it is aware of the problem and that its engineers are working to resolve the issue.
From our own testing, we can confirm that not everyone is experiencing the service outage. Some users are able to access all of their digital library with no issue, whereas others are greeted by error codes or a message explaining that service outages happen from time to time.
If Xbox Live users are already in-game, they don't appear to be kicked out, but if they try to open a different game, that's when the problem occurs. At the time of this writing, Xbox hasn't provided any kind of explanation for the service outage, and also hasn't revealed when fans can expect Xbox Live to be back up for all subscribers.
While some users may be frustrated that Xbox Live is currently down in some areas, it's worth pointing out this isn't a common problem. Typically, Xbox Live works as expected, but occasionally there are issues where certain parts of the service are inaccessible, whether it be inability to access digitally owned content or being unable to connect to online games.
It's probable that Xbox will be able to resolve the current issues with Xbox Live before too long. Of course, there was the Lizard Squad DDoS incident that saw both Xbox Live and the PlayStation Network downed during the 2014 holiday season, but it doesn't appear as though the current problems are anything on that scale. As previously stated, some users aren't even running into the outage at all, and are able to access all of their digitally-owned games without issue.
We'll update this article as soon as services are fully restored on both Xbox One and Xbox 360.
