On December 11, 2024, OpenAI's ChatGPT experienced a global outage, starting late at night and lasting over three hours. Users attempting to access the AI chatbot were met with error messages, including 'ChatGPT is currently unavailable' and 'Upstream connect error 111.' The outage affected not only ChatGPT but also OpenAI's API and Sora platforms. OpenAI acknowledged the issue, stating, 'We have identified the issue and are working to roll out a fix.' By December 12, 2024, OpenAI confirmed that the services had been restored. Later, the company attributed the outage to a 'new telemetry service' that had caused technical issues while collecting Kubernetes metrics.
