A worldwide Xbox outage last week left many players unable to launch even physical disc games, which should have remained playable offline. The incident reignited concerns over the fragility of physical media in an always-online era. Microsoft quickly responded, clarifying that discs should never have been affected and that an update is on the way.
Outage disrupted disc games despite offline mode
During the 16-hour service interruption, users reported being unable to start any game, including those inserted via disc. Instead of relying on locally saved licenses, the console attempted to contact an external server for entitlement verification, which failed due to the outage. This surprised many, as disc-based games are traditionally considered immune to connectivity issues.
Microsoft explains: entitlement check errors
Scott Van Vliet, Microsoft's chief technologist, told The Verge that disc-based entitlement checks should not prevent players from accessing their games. He explained that the console performs license verification to determine which content the user is entitled to, but this information is stored locally precisely to ensure offline functionality. The company identified a bug that prevented the console from correctly using saved entitlements during the external service outage.

Smart Delivery and full-disc support: why the mechanism failed
Microsoft's Smart Delivery system automatically installs the best version of a game for the hardware. An alternative implementation called full-disc support allows developers to place all executables on the disc, eliminating the need for an internet connection. It was this mechanism that failed during the outage, locking players out. The issue stemmed from an external license service provider that suddenly went down, and the console defaulted to a fail-close instead of a fail-open behavior for discs.

DRM and the future of physical media: growing concern
This incident renews the debate on digital rights management (DRM) applied to physical media. Sony previously faced backlash over alleged mandatory 30-day check-ins on PS5, later denied. Steam also drew criticism in 2024 over ambiguous perpetual licenses. Similar entitlement check issues have appeared on other platforms. With the announcement that PlayStation discs will cease to exist by 2028, concerns over physical game ownership are escalating. Microsoft has confirmed it is already working on an update to fix the error, though no timeline has been provided.
