Title: Users may be unable to play migrated Stream videos in Microsoft Stream

User impact: Users may be unable to play migrated Stream videos in Microsoft Stream.

More info: Users attempting to play impacted Stream videos will encounter the error message: “This browser or app can’t play the video. Something might be outdated or not supported. Try again using a different browser or app.”

Current Status: Our telemetry indicates that our fix is making steady progress across impacted environments. We’ve not been able to increase the roll out speed at this time, however the fix is still on track to reach all environments by Friday April 5, 2024. Once it has fully saturated the repair job will likely take another week to fully remediate the impact, with most impacted files becoming available to play well before then.

Scope of impact: Any user may be unable to play migrated Stream videos in Microsoft Stream.

Start time: Saturday, February 10, 2024, at 2:00 AM UTC

Preliminary root cause: A recent feature update, intended to enhance the reliability and stability of our service, contained a code regression that impacted Stream video files that were migrated between Saturday, February 10, 2024, at 2:00 AM UTC, and Tuesday, February 20, 2024, at 9:30 AM UTC, causing them to be unable to play.
