Microsoft is currently experiencing an outage where some users are unable to login to Xbox Live, have issues with matchmaking, and are unable to access support.xbox.com.
At approximately 5:00 PM EST, users started reporting that they were unable to login to Xbox Live, access their saved games, or have issues with matchmaking. Since then, users have also been having issues opening support.xbox.com.
Microsoft has confirmed these issues in the Xbox Support Twitter account as can be seen below.
When users try to access support.xbox.com, they will simply be greeted with the animated Xbox loading circle as seen below.
At approximately 7:30 PM EST, service was restored for both Xbox Live and support.xbox.com
