A blackout period prevents all scheduled tasks and taskflows in the organization from running during a specified period of time. You can configure a blackout period during which the scheduled Data Integration and Mass Ingestion file publications and file subscriptions don't run. You can also configure one blackout period for an organization.
If a task is scheduled to run during a blackout period, the task instance will not be started during the blackout period, and it will not restart automatically when the blackout period ends. After the blackout period, task instances will resume according to the schedule. If a task is already running when a blackout period starts, it will not be stopped.
To configure a blackout period, in Administrator, select Schedules, and then click Blackout Period. The blackout period is displayed on the Schedules page.
