On December 12, OpenAI updated the service status page, in which it added a review of the accident of ChatGPT, Sora and API service downtime for more than four hours the previous day. OpenAI said that this incident was not caused by a security vulnerability or a new product release, but by an internal system upgrade. OpenAI engineers deployed a new telemetry service in the afternoon of the 11th. However, due to misconfiguration, each node performed a large number of Kubernetes API operations at the same time. Finally, the server was overwhelmed and the control plane crashed. This in turn causes DNS resolution failures, resulting in the inability of services to communicate with each other. In the process ..

If we compare it with Debian (an operating system project based on its support cycle in many organizations), we will find a direct difference between the two. It can be seen that as an infrastructure project, the iteration cycle of Kubernetes still makes many companies unable to catch up ..
