ChatGPT, Grok, and Claude all went down at the same time

OpenAI’s ChatGPT, xAI’s Grok, and Anthropic’s Claude all experienced simultaneous outages on the morning of the incident, affecting users across multiple platforms. At approximately 11 a.m. Eastern Time, ChatGPT began returning error messages, with OpenAI’s status page reporting “elevated errors across ChatGPT and Codex.” The disruption halted conversational access and also impaired logins, file uploads, voice mode, search, deep‑research functions, image generation, and other features. OpenAI announced that it had applied a mitigation and was monitoring recovery, though performance remained degraded. At roughly the same time, Anthropic users reported problems with Claude, Claude Code, and the Claude API; the company’s status page initially listed several model versions as impacted before narrowing the issue to Opus 4.8 and Opus 5, attributing the partial outage to an “infrastructure issue” without providing an estimated time of resolution. Grok’s Android, iOS, and web applications likewise went down, with prompts on X returning a “model is overloaded” notice and a website alert stating xAI was working to restore service.

The concurrent failures underscore the fragility of the underlying infrastructure that powers today’s leading conversational AI systems. OpenAI’s outage coincided with the company’s teaser for Astra, its forthcoming AI model, raising concerns about the timing of new releases amid stability challenges. Anthropic’s clarification that only specific Opus model versions were affected suggests a targeted failure rather than a platform‑wide collapse, yet the lack of a clear ETA highlights the difficulty of diagnosing and repairing large‑scale cloud‑based AI services. Similarly, Grok’s generic “overloaded” message points to capacity or load‑balancing problems, but no concrete cause has been disclosed, leaving users and industry observers uncertain whether the incidents share a common root or are independent glitches.

The three outages left developers, enterprises, and casual users without access to critical AI tools, potentially delaying projects that rely on real‑time language processing, code generation, or image creation. With OpenAI, Anthropic, and xAI all confirming they are working on restoration, the incident may prompt a reevaluation of redundancy and fail‑over mechanisms across the sector. Stakeholders are watching closely for any post‑mortem analyses that could reveal systemic vulnerabilities, especially as competition intensifies among the remaining major chatbots—Gemini and Microsoft’s Copilot—now positioned as the sole large‑scale conversational agents still operational.
