On December 26, 2024, A ChatGPT outage disrupted access for countless users worldwide. This was a major outage affecting not just the ChatGPT web interface but the entire OpenAI platform including their APIs. The incident was traced back to a power issue in Microsoft Azure’s South Central US data center which took down many other Azure customers. StatusGator customers received Early Warning Signal notifications before either provider updated their public status pages:
- StatusGator notified 3 minutes before OpenAI acknowledged the incident
- StatusGator notified 34 minutes before Microsoft acknowledged the Azure power issue
December 2024 ChatGPT Outage Overview
At approximately 1:35 PM ET, many users began reporting issues with ChatGPT. Messages stopped generating responses, users described internal server errors and intermittent availability. By 1:57 PM ET, StatusGator had already issued an Early Warning Signal, notifying customers of potential disruptions in OpenAI’s services. At this time, OpenAI had yet to update its company status page.
The root cause was later identified as a power failure at Microsoft’s Azure South Central US data center. This power problem affected numerous Azure-dependent companies and services, including ChatGPT. Microsoft and OpenAI have a deep partnership with the former investing billions of dollars into the AI and helping to support its quest for Artificial General Intelligence.
Despite the cascading impact, StatusGator’s proactive alerts ensured our customers were prepared before official updates were posted.
