Stop an experiment

If you stop an ongoing experiment, you will not be able to resume it or restart it. The portion of traffic that was previously used in the experiment will be served the default variation.

When an experiment is not manually stopped and passes its end date, the traffic does not change. The portion of traffic allocated to the experiment still goes to the experiment. To stop this, and cause the experiment traffic to instead be served the default variation, mark the experiment as complete.

When you stop an experiment, you can choose to cancel it or mark it as complete. If you cancel, it will be shown as Cancelled in the list of experiments. If you choose to mark it as complete, it is shown as Completed.
