Spotify’s two incident questions are the best part. the first one is harder than it looks though, you need to know which change caused the incident, and most teams figure that out by hand. we looked at a Spotify outage from that angle at Tomosu, whether the risk was visible before it shipped. the PR looked reasonable on its own, the risk only showed up in how it interacted with the rest of production. that’s the gap we’re working on https://tomosu.ai
