A widespread outage affecting ChatGPT, Claude, and Grok disrupted AI services for thousands of users Thursday morning. OpenAI, Anthropic, and X confirmed technical problems across their platforms, with Microsoft Azure potentially linked to the simultaneous failures.

Multiple Major AI Platforms Experience Simultaneous Outages

A significant AI outage struck Thursday morning, taking down ChatGPT, Claude, and Grok simultaneously and leaving thousands of users unable to access these popular AI platforms

1

2

. OpenAI confirmed that ChatGPT down issues began at approximately 10:58 AM ET, affecting nearly every major feature across its platform

1

. The widespread outage affecting ChatGPT extended to at least 15 components, including conversations, login, search, file uploads, Voice mode, GPTs, image generation, Deep Research, Agent, ChatGPT Work, and Codex services

1

. Users attempting to access the platform encountered errors when loading conversations, sending messages, or utilizing core features.

Anthropic and X Report Confirmed Outages Across Services

Anthropic reported elevated errors across multiple Claude models starting just before 9:30 AM Eastern Time

3

. The technical problems affected several versions including Mythos/Fable 5.1, Mythos/Fable 5, Opus 5, Opus 4.8, and Opus 4.6

3

. By 10:49 AM, Anthropic stated it had identified the cause and was continuing to work on a fix for the issue

Microsoft Azure Emerges as Potential Common Factor

The timing of these simultaneous outages points to Microsoft Azure as a potential culprit behind the widespread disruption

2

. Azure experienced a spike in outage reports coinciding with the AI platform failures, and all three affected services rely on Azure for cloud services

2

. This dependency on shared cloud infrastructure highlights the vulnerability of AI platforms to cascading failures when a major cloud provider experiences technical difficulties. Google's Gemini remained largely unaffected, though the platform did report partial degradation for some developer and API users

3

. Google AI Studio's status page indicated problems serving recently created API keys, including keys used through OpenAI-compatible libraries

Outage Timing Coincides with OpenAI's Astra Model Launch

The ChatGPT down incident occurred just ahead of OpenAI's expected launch of its next major AI model, Astra

1

. OpenAI recently confirmed the Astra model will be released soon, though the company has not indicated whether Thursday's outage relates to preparations for the launch

1

. There is currently no evidence linking the two events, but the timing has sparked speculation about potential infrastructure updates or testing that may have contributed to the service disruption. As organizations increasingly depend on AI platforms for daily operations, these simultaneous outages underscore the need for robust redundancy and disaster recovery planning. The incident serves as a reminder that even leading AI providers remain susceptible to technical failures, particularly when relying on shared cloud infrastructure from providers like Microsoft Azure.
