Every production incident starts with a simple question: "Has this happened before?"I've lost count of how many incident bridges I've joined where that question came up within the first few minutes. Before anyone proposes restarting a service or rolling back a deployment, someone inevitably starts searching. They look through Slack conversations from previous outages, browse old postmortems, compare dashboards with similar incidents, or dig through runbooks to see whether another team has already solved the same problem.
