On-Call Rotation
Noun · Hacker Culture
Definitions
A schedule where team members take turns being the primary responder for production incidents outside business hours. Good rotations include clear escalation paths, runbooks, and compensation. 'You build it, you run it' is the DevOps philosophy behind engineering on-call.
In plain English: Taking turns being the person who gets woken up at night when the servers break.
Example: "I'm on call this week — my phone buzzed at 3am because the payment service hit its error budget."
