Return to service (after an incident)
Also known as: Return to operation, Restart release after an incident
German: Wiederinbetriebnahme nach einem Vorfall
Return to service is the controlled release of a system, process or AI agent back into operation after an incident: it confirms that the cause is understood and contained, that affected data and configurations are restored or corrected, that the conditions for a safe restart are met and that an authorized person has approved the restart.

In one sentence
Return to service: the authorized release of a system or AI agent back into operation once cause, data and restart conditions are checked.
Example
The agent that changed recipe parameters returns to service only in read-only mode, after the recipes were compared with the released versions and the shift leader approved the restart of the line.

How it applies
- Release criteria: Cause known, agent scope corrected, credentials renewed, data and configurations compared with released versions, monitoring in place, approval recorded.
- Step back first: An agent often returns with less: read-only, with more approval gates, or for a smaller group of users or devices.
- Machines and lines: A restart after an incident follows the machine's own rules — restart prevention, the coordinated restart of a line, the operator's release. An agent never restarts a machine on its own.
- IoT fleets: Return to service is staged: a small device group first, then wider, with a rollback image ready.
