Each team can have one or more on-call schedules. A schedule decides who is reachable when an alert fires for one of the team’s services.

​
Schedules

A schedule is a recurring rotation through a list of people. You can have multiple schedules per team if different groups cover different hours or services (e.g. “Weekday primary”, “Weekend primary”, “Database secondary”).

​
Rotations

Rotations cycle the on-call person on a fixed cadence:
  • Daily - new person every 24 hours.
  • Weekly - new person every 7 days.
  • Custom - any length you specify.

​
Escalation policies

An escalation policy decides what happens if the primary on-call doesn’t acknowledge an alert within a window. The next person up gets paged, and so on. You can stack as many levels as you need and choose the wait time at each level.

​
Overrides

Overrides are temporary swaps - vacation cover, handoffs, “I’ve got tonight.” They only apply for the window you specify and don’t change the underlying rotation.

​
Fallback

If no one is on-call (no schedule, or everyone is overridden out), Warrn pages the team’s admin. This is the last-resort fallback, not the steady state. Set up a schedule even if it has only one person on it.
