Your First On-Call

What it's actually like to carry the pager for the first time: getting set up before your shift starts, staying calm through the 3am page, and turning the aftermath into a blameless postmortem instead of a blame session.

1. Before Your First Shift What to verify before your first on-call rotation starts: alerts reach you reliably, you know where the runbooks live (and that missing ones are normal), and you know your escalation path.
2. The 3am Page: A Calm Playbook How to stay calm when the pager goes off: triage before you try to fix anything, stop the bleeding before you root-cause, and know when to escalate instead of struggling alone.
3. After the Fire: the Postmortem Why blameless postmortems beat blame-driven ones, why human error is rarely the real root cause, and how to write up an incident so the next on-call engineer benefits from your bad night.
