The Site Reliability Podcast with Fexingo: SRE, Uptime, and Production Engineering
Lucas and Luna cut through the noise around site reliability engineering to examine how real-world SRE teams balance uptime, incident response, and production change. Each episode takes a single concept — error budgets, toil automation, postmortem culture, capacity planning — and grounds it in a specific case: how a major streaming service reduced paging noise, how a payments platform rebuilt its incident command structure, or how a cloud provider manages multi-region failover. Lucas brings the numbers — latency percentiles, MTTR trends, SLO burn rates — while Luna pushes on the human and organizational trade-offs: What does a junior SRE need to know about on-call? How do you measure reliability without crushing innovation? Why do some blameless postmortems actually work? Together they treat SRE not as a certification topic but as a living practice, citing real outages, open-source tools, and engineering blogs. This show is for engineers, ops leads, and platform teams who already know the basics and want to debate the hard edges: Is 99.999% uptime always worth the cost? When should you deliberately degrade service to improve reliability? How do you design for resilience when your s
