After a noticeable interruption in service on Wednesday morning, November 8, 2023, OpenAI’s widely popular chatbot, ChatGPT, resumed operations. This hiccup began before the clock struck 9 a.m. ET and had a ripple effect on OpenAI’s API services, which at the time served an extensive network of over two million developers.
Users attempting to access ChatGPT encountered capacity errors. The issue was classified as a major outage on OpenAI’s status page.
OpenAI’s incident record confirmed that the disruption spanned from 5:42AM to 7:16AM PT, during which all services were affected. However, the problem was promptly identified and rectified. “We are now seeing normal responses from our services,” reassured OpenAI on its status page.
The original report also described capacity problems affecting Anthropic’s Claude 2 chatbot that Wednesday. This was a separate service; similar symptoms do not establish a shared cause.
This service interruption followed OpenAI’s inaugural in-person DevDay event on Monday, November 6, 2023. The company announced GPT-4 Turbo and introduced custom versions of ChatGPT. These are historical launch announcements, not descriptions of the latest models.
The original November 2023 report attributed to OpenAI’s then-Chief Technology Officer, Mira Murati, the statement that an impressive 92% of Fortune 500 companies were utilizing the platform, a substantial increase from the 80% recorded in August. These companies are spread across diverse sectors including financial services, legal applications, and education.
Later technical explanation: OpenAI’s incident write-up said routing-layer nodes reached memory limits and failed readiness checks, leaving insufficient capacity. This follow-up concerns the November 8 morning outage described above; it should not be conflated with separately reported periodic outages associated with abnormal traffic.
