  Update from Azure: We identified a recent change that was strongly correlated with the onset of impact and have initiated rollback actions. The rollback is currently in progress and making steady progress toward completion. Telemetry across services is beginning to show signs of recovery. We are closely monitoring service health and traffic recovery as these actions are completed and will provide additional updates as we confirm measurable improvement.
