On Thursday local time in the United States, ChatGPT, Sora, and OpenAI's API services for developers experienced another outage, lasting over four hours. OpenAI reported that a major disruption began at 11 AM (all times mentioned in this article refer to local time in the United States), but by 3:16 PM, services were gradually recovering. Regular users of ChatGPT might recall that the service also faced interruptions earlier this month.

On its status page, OpenAI indicated that this major disruption was caused by one of its upstream vendors, but did not provide further details. As of 2:05 PM, OpenAI stated that ChatGPT had partially recovered, but users might still encounter issues when loading chat history. By 3:16 PM, Sora resumed operations. The company stated that it is actively working to fully restore ChatGPT and its API.

This is the second outage for OpenAI's services in December. Two weeks ago, OpenAI attributed an outage to issues with a new telemetry service. That outage lasted about six hours, which is unusually long. Typically, these outages last only one to two hours.

According to official reports, as of 5:11 PM, it was stated that ChatGPT is recovering and efforts to fully restore services are ongoing.
