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 Something might be outdated or not supported.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 previously mentioned repair job has saturated and is subsequently beginning its incremental restoration of residually affected files. The majority of users should now be able to play their Microsoft Stream videos as anticipated, and we tentatively expect resolution for all users by our next scheduled update.

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 which 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, preventing them from playing as expected.

Estimated time to resolve: We anticipate that the issue will be resolved by Monday, April 8, 2024.

Next update by: Monday, April 8, 2024, at 11:30 PM UTC
