Humans of Reliability

Most incident response advice focuses on tools, alerts, and post-mortems. Gandhi Mathi Nathan Kumar, Principal Incident Commander at Twilio, with 14 years running calls that have pulled in up to 100 responders, argues the work that actually matters happens in the first 15 minutes. In this episode, Gandhi walks through what he calls the golden hour: the window where you decide whether you know what's broken, who belongs on the call, and whether to chase the root cause or reach for redundancy. He gets into why mitigation has to come before diagnosis, why customers trust your status page more than your engineers, and why he once sat with a stopwatch counting how many clicks it took to declare an incident. Along the way: the human side leaders keep underinvesting in, the math of on-call fatigue, and where AI is actually pulling weight in the incident commander seat.
