Update 3 (February 23, 2016 @ 7:42 a.m. Central): As of approximately 5:30 a.m. Central, Microsoft alerted users that the problems affecting Xbox Live have been repaired. Total downtime was more than 15 hours, during which time many users were unable to play purchased content or access streaming services.

In some cases, users were unable to stream content from local PCs or play DVDs and Blu-Ray discs. It's unclear whether the problems were simple server failure or originated with an attack. We'll update should Microsoft share more details.

For now, Xbox Live appears to operating normally.
