On-Call

On-call is the rotation that designates who is responsible for responding to incidents at any given time, including outside business hours.

An on-call schedule pairs with escalation policies so alerts reach the right person now and escalate if they do not respond. It is how teams cover 24/7 reliability without burning everyone out.
