How SRE Teams Use Incident Severity Classification to Prioritize Response

Episode 59 of The Site Reliability Podcast explores how SRE teams classify incidents by severity to decide how fast to respond and who to page. Lucas and Luna break down real-world classification frameworks — from SEV-1 (service down, all hands on deck) to SEV-4 (minor hiccup, fix in the next sprint). They discuss why vague severity definitions lead to alert fatigue and slow response times, and how companies like Google and Stripe have standardized their severity matrices. Lucas shares a concrete example from a payment processing outage where misclassifying a SEV-2 as a SEV-3 delayed response by 45 minutes. Luna highlights the role of severity escalation policies and how automated detection can adjust severity based on customer impact. The hosts also touch on the tension between over-classifying (too many SEV-1s) and under-classifying (missing critical signals). A practical episode for any engineer who's ever argued about whether an incident is 'really' a SEV-2. #IncidentSeverity #SEV1 #SEV2 #SRE #SiteReliability #IncidentResponse #OnCall #Alerting #PagerDuty #GoogleSRE #Stripe #Classification #SeverityMatrix #Uptime #Tech #FexingoBusiness #BusinessPodcast #ProductionEngineering Keep every episode free: buymeacoffee.com/fexingo
