Yesterday's global internet outage caused by single file on Cloudflare servers — unexpected file size caused catastrophic error, knocking out several major websites

Cloudflare, one of the biggest DDoS and security providers on the internet, suffered a major outage yesterday, knocking out several major websites, including X, OpenAI, and even some McDonald’s branches across the globe. Its chief technology officer has since apologized for the massive error, while its co-founder, Matthew Prince, has since released the details of the cause of the outage on the company blog.

Since Cloudflare is a web security outfit that protects a big chunk of the internet from DDoS and other similar network intrusions, one of the first thoughts of the company was that it was under attack. In fact, Microsoft released a report of a record-breaking DDoS attack against its servers on the same day that the Cloudflare issue happened. However, the company realized that it was actually caused by a configuration error after further investigation.
