Cloudflare CEO explains exactly what caused global outage

A Cloudflare outage took out a large swathe of the internet on Tuesday, with users unable to access numerous sites and services such as X, ChatGPT, Spotify, YouTube and Uber. The cybersecurity company has now published a blog post detailing exactly what happened.

Cloudflare co-founder and CEO Matthew Prince apologised in the post late Tuesday, stating that this outage was the worst the company has experienced since 2019. “[I]n the last 6+ years we’ve not had another outage that has caused the majority of core traffic to stop flowing through our network,” said Prince. “On behalf of the entire team at Cloudflare, I would like to apologize for the pain we caused the Internet today.”

Prince explained that the Cloudflare outage had been caused by an issue with the system it uses to protect websites from DDoS attacks.
