Update: Xbox Live services have been restored.
Xbox Live users are currently experiencing issues on the Xbox One, Xbox 360, as well as on Windows devices. The Xbox Live Status page describes both the Website and Core Services features as “Limited,” while the support says they are aware of and working to get it fixed.
Some Xbox Live users are reporting that they are able to log-in to specific games and back on to the their Xbox Live accounts, where others are still reporting that specific games are still having issues.
Xbox Live has seen numerous outages in the last couple of weeks. Just days ago, the network went down for a short period where Xbox Live users could not access purchased content or specific account features.
There has been no word on what has caused this latest outage.
