Title: Users may be unable to view telemetry data as expected in the Microsoft Defender for Endpoint portal
User impact: Users may have been unable to view telemetry data as expected in the Microsoft Defender for Endpoint portal.
Final status: We’ve completed correcting the misconfiguration and confirmed through our service monitoring telemetry that data is now ingesting and populating as expected in the Microsoft Defender for Endpoint portal.
Scope of impact: Any user hosted out of the affected infrastructure may have been unable to view telemetry data as expected in the Microsoft Defender for Endpoint portal.
Start time: Wednesday, September 27, 2023, at 1:00 PM UTC
End time: Wednesday, September 27, 2023, at 7:20 PM UTC
Root cause: A recent service update, intended to reconfigure a network authentication component, led to a discrepancy between the information present on the infrastructure that facilitates this functionality and the information recognized by the service to fulfill telemetry data ingestion and population in the Microsoft Defender for Endpoint Portal.
Next steps:
– We’re assessing the validation process for which authentication component configuration changes are tested so we can ensure that future changes don’t result in similarly impacting events.
This is the final update for the event.
