Xbox Says Licensing Service Failure Caused Hours-Long Outage

Xbox has explained the hours-long outage that stopped some players from signing in, viewing their full libraries, and launching games they owned. According to Xbox CTO Scott Van Vliet, the problem came from an internal Microsoft licensing service used across multiple products.

In a post on social media, Van Vliet said the failed service affected sign-in checks and entitlement checks, which are the systems Xbox uses to confirm what games and content an account has access to. That’s why some players could not see their libraries or start games, even if they had purchased them.

The issue also hit some publishing and store partners that rely on the same systems, which explains why reports varied from game to game. After Microsoft isolated the failed infrastructure, Xbox shifted traffic to healthier parts of the system, but service came back at different times depending on region.

Van Vliet said Xbox is now running a full post-incident review to figure out why one service failure caused such a wide outage, why recovery took as long as it did, and what needs to change to prevent a repeat. He said the team will focus on strengthening sign-in and game launch dependencies, improving detection, and communicating faster when problems happen.

The outage came shortly after PlayStation Network also had downtime tied to connectivity issues on Amazon Web Services servers, which left some players unable to access digital games during the Marvel Tōkon: Fighting Souls open beta.
