Embodiments are directed to automated investigation of regression or other defects. A time-series of values for a metric associated with an execution of a verification action for a service may be provided. If a metric value in the time-series of values is outside of a control range, further actions may be performed, including: determining a last valid version of the service based on the time-series of values; determining a first invalid version of the service based on the time-series of values; determining changes associated with differences between the last valid version of the service and the first invalid version of the service based on the time-series of values; determining responsible users based on the determined changes; and generating a defect report based on the changes and the metric value that is outside of the control range such that the responsible users are associated with the defect report.
