• Consider the information available from the JS7 - Impact of a Controller outage
• For information about the behavior in case of outages see JS7 - FAQ - What happens to workflows in case of outage of a Controller?
• Use of a Controller cluster will leverage an outage situation as the Secondary Controller will pick up operations immediately during fail-over (3-5s). The failed Primary Controller instance can be started later on will automatically synchronize with the Secondary Controller instance.
