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.
