What is on-call?

On-call is the arrangement in which a named person is responsible, for a set period, for responding to alerts and incidents outside normal working hours, or around the clock.

How it works and why it matters

An on-call schedule rotates the responsibility through a team, often weekly, with a handover at a fixed time. Overrides cover holidays and sick days, and an escalation policy brings in someone else when the person on call doesn’t respond.

Good on-call depends on the alerts: each page should be urgent, actionable and rare. A rotation in which people are woken for things that can wait until morning wears people out and teaches them to ignore alerts; that is alert fatigue.

Runbooks, clear ownership and time off after a rough night keep a rotation sustainable.

How Uptimecheck helps

Uptimecheck on-call schedules rotate through people every day, week or two weeks, handing over at a time you choose in the schedule’s time zone. Cover a shift lets someone take over for a while, and a push channel set to “Whoever is on call” alerts only that person’s devices.

Questions

How long should an on-call shift be?

A week is the most common rotation; shorter shifts suit teams with frequent alerts. Hand over during working hours, so questions can be asked.

What is the difference between on-call and an escalation policy?

The schedule says who is responsible now. The escalation policy says what happens when that person doesn’t respond in time.

How do you make on-call less painful?

Page only for what needs a person now, confirm failures before paging, send everything else to a channel read during the day, and go through every page in the week after.
