Root cause: A code issue in a recent deployment to Microsoft Defender XDR that handles the API for the submissions portal was preventing data from loading as expected.
Next steps:
– We’re further reviewing the recent deployment to understand how the code issue was introduced, and to understand what prevented it from being detected in our update testing and validation procedures, which will allow us to prevent similar issues in future updates.
This is the final update for the event.
