How SRE Teams Use Game Days to Build Muscle Memory for Incidents

In Episode 26 of The Site Reliability Podcast, Lucas and Luna explore how SRE teams run 'game days' — simulated incident exercises — to build muscle memory and reduce panic during real outages. They break down how Etsy, a pioneer in game days, structures its exercises using realistic scenarios, mini-game design, and post-mortem debriefs without blame. The hosts discuss the difference between chaos engineering and game days, how to avoid making exercises feel like busywork, and why even small teams can run a low-stakes simulation with nothing more than a staging environment and a script. Lucas shares concrete steps: start with a single failure mode, assign roles, time-box the response, and debrief with the question 'What did we learn?' rather than 'Who messed up?' The episode also touches on the metrics that matter — mean time to acknowledge, mean time to resolve, and how game days improve both without requiring expensive tools.
