Noisy Silence: The Mysterious Outages of OpenAI, Anthropic, and xAI


Three prominent AI companies, OpenAI, Anthropic, and xAI, simultaneously experienced rare outages on Thursday morning, leaving users and experts wondering about the cause of this unusual event. The incident highlights the importance of maintaining robust infrastructure and cybersecurity measures in the AI sector and underscores the need for greater transparency and collaboration among companies and experts.

  • Three prominent AI companies (OpenAI, Anthropic, and xAI) experienced rare outages on Thursday morning, affecting their AI chatbots.
  • The causes of the outages were attributed to different companies, but the door was left open for speculation about a potential shared cause.
  • OpenAI cited a routing error as the cause of the outage, while Anthropic claimed to have identified the cause and deployed a fix.
  • xAI reported Grok outages due to an investigation into the issue.
  • There were scattered reports of a possible Google Gemini outage, but the company did not confirm the issue.
  • The lack of evidence from major internet infrastructure players suggests that the cause of the outages might be more complex.
  • The incident highlights the importance of robust infrastructure and cybersecurity measures in the AI sector.
  • The exact cause of the outages remains a mystery, and it may never be revealed.



  • The technology landscape witnessed a peculiar phenomenon recently, as three prominent AI companies - OpenAI, Anthropic, and xAI - simultaneously experienced rare outages on Thursday morning. The affected AI chatbots, including ChatGPT, Claude, and Grok, suffered from downtime, leaving users and experts alike wondering about the cause of this unusual event.



    The issues with Grok, a platform from xAI's parent company SpaceX, were attributed to an outage at their Memphis compute center, according to a statement by SpaceX. However, neither OpenAI nor Anthropic cited an external source for the cause of their outages, leaving the door open for speculation about a potential shared cause.



    OpenAI spokesperson Kathleen Chaykowski revealed that a routing error starting around 7:43 am PT on Thursday caused ChatGPT and Codex to become unavailable for some users across platforms. The company reported that a solution was successfully implemented and is continuing to be monitored.



    Anthropic, on the other hand, alerted users about a "partial outage" at 6:23 am PT on Thursday, involving "elevated errors on requests to Claude Mythos 5.1, Claude Fable 5.1, and Claude Opus 5." The company claimed to have identified the cause and deployed a fix, which was marked as resolved by 9:16 am PT.



    The xAI platform, which is also owned by SpaceX, reported Grok outages across all platforms and services beginning at 6:30 am PT. The company stated that it was "investigating outage" on its service status page and working to restore service as quickly as possible.



    There were scattered reports of a possible Google Gemini outage on Thursday morning, but the company did not confirm the issue or record any incidents on its service status dashboard. Google did not respond to WIRED's request for comment.



    Given the unusual timing and coincidence of the outages, it is reasonable to assume that the outages might be linked to a shared third-party service provider. However, without concrete evidence, it is premature to draw any conclusions about the cause of these events.



    Major players in the internet infrastructure space, including Cloudflare, Amazon Web Services, and Microsoft Azure, did not report outages on Thursday. This lack of evidence from the usual suspects suggests that the cause of the outages might be more complex and harder to pinpoint.



    The recent experience highlights the importance of maintaining robust infrastructure and cybersecurity measures in the AI sector. It also underscores the need for greater transparency and collaboration among companies and experts to address potential issues before they become major incidents.



    In the end, the exact cause of the outages remains a mystery, and it is unlikely that the truth will be revealed anytime soon. However, the incident serves as a reminder of the complexity and fragility of modern technology systems and the need for continued vigilance and cooperation in the pursuit of technological advancement.
