    On 11 December 2024 OpenAI deployed a new telemetry service into its Kubernetes clusters. Its configuration caused every node to perform Kubernetes API operations whose cost scaled with the size of the cluster; API servers saturated and DNS-based service discovery failed across most large clusters, with services unavailable from 15:16 to 19:38 PST. The change had been tested in staging. What structurally failed, what could staging not test, and where would copying their response be a mistake?
