The Site Reliability Podcast with Fexingo: SRE, Uptime, and Production Engineering

SRE teams drown in alerts—most of them false positives. Lucas and Luna break down how Slack’s reliability team redesigned their alerting pipeline to cut noise by 90 percent without missing critical incidents. They walk through the specific techniques: tiered severity classification, suppression rules based on dependency graphs, and a weekly 'alert review' meeting that treats every notification as...

Episode 3 of The Site Reliability Podcast with Fexingo dives into the concept of error budgets — the SRE mechanism that turns uptime targets into engineering velocity. Lucas and Luna unpack how Google introduced error budgets to solve the tension between reliability and feature releases, using real examples from a major streaming service and a payments API. Lucas explains the math behind 99.9% vs...

Lucas and Luna dive into what makes an incident response playbook effective versus one that just sits in a wiki. Lucas walks through a real example from Stripe's 2023 outage where the playbook itself became the bottleneck. They discuss the anatomy of a good playbook, why most fail, and how to test them without waiting for a real incident. Luna pushes back on whether playbooks create a checklist me...

On the premiere of The Site Reliability Podcast, Lucas and Luna examine a specific incident: a 47-second outage at a major US bank in early 2026 that halted digital payments for four hours. They break down what actually happened inside the SRE war room, how the bank's incident response failed at the human level, and why that half-minute of downtime cost an estimated $3.2 million in direct losses....
