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 system is already in production? Lucas and Luna don't pretend to have final answers — they build the conversation so you can draw your own. If you've ever argued about whether a page was necessary or whether an SLO should be tightened, this is your show.
