Widespread failures have hit X (formerly known as Twitter), OpenAI, and gaming platforms as Cloudflare, the infrastructure provider, investigates widespread 500 errors affecting customers around the world.

The big picture: Cloudflare, which provides critical infrastructure for some of the world’s largest websites, is experiencing a significant technical failure that began around 11:30 GMT on Tuesday morning.

Why it matters: The outage demonstrates the internet’s reliance on a handful of infrastructure providers. When Cloudflare falters, vast swathes of seemingly unconnected services go dark simultaneously.

What’s affected:

  • Social media platform X (formerly Twitter) is showing intermittent failures
  • ChatGPT users cannot access OpenAI’s services
  • Popular games including League of Legends and Valorant report connection issues
  • Film review site Letterboxd is down
  • Even outage tracker DownDetector has been compromised, complicating efforts to monitor the incident.

What they’re saying: “Cloudflare is aware of, and investigating an issue which impacts multiple customers: Widespread 500 errors, Cloudflare Dashboard and API also failing,” the company said at 11:48 GMT. “We are working to understand the full impact and mitigate this problem.”

What users see: Many visitors encounter error messages reading “Please unblock challenges.cloudflare.com to proceed” or generic “internal server error” on Cloudflare’s network warnings, though the underlying websites remain operational.

The context: Cloudflare provides distributed denial-of-service (DDoS) protection, content delivery and security services for major platforms worldwide. The incident echoes a similar disruption at Amazon Web Services last month.

The bottom line: Cloudflare has yet to identify the root cause or provide a timeline for restoration, with the company’s own status page showing signs of degradation.
