A significant portion of the web has ground to a halt today following a widespread technical failure at Cloudflare, a key provider of internet infrastructure.

Major platforms, including X (formerly Twitter) and the popular film logging site Letterboxd, have been rendered inaccessible for thousands of users. The outage began affecting services around 11:30 AM GMT, causing frustration for users worldwide who were unable to access their accounts or refresh feeds.

What is Happening?

Users attempting to visit affected websites are currently being met with a blank screen or an error message stating:

“Internal server error on Cloudflare’s network. Please try again in a few minutes.”

In an ironic twist, Down Detector—the go-to website for tracking internet outages—was also impacted by the glitch. However, during moments of connectivity, the site displayed a massive spike in error reports across a wide variety of services.

Cloudflare Responds

Cloudflare, which operates visibly behind the scenes to protect websites from cyber attacks and manage traffic flow, confirmed the incident shortly after reports began spiking.

“Cloudflare is aware of, and investigating an issue which potentially impacts multiple customers,” the company wrote in an official status update. “Further detail will be provided as more information becomes available.”

Why This Matters

Cloudflare acts as the “plumbing” for a vast number of websites. Because its services are integrated into so many different companies, a single technical fault at Cloudflare can knock out apparently unconnected websites simultaneously.

This outage highlights the fragility of the modern internet’s reliance on a few major infrastructure providers. It comes just one month after a similar large-scale outage at Amazon Web Services (AWS) took a significant chunk of the internet offline.

MazeInfo will continue to update this story as services are restored.
