The CTO wrote, “I won’t mince words: Earlier today we failed our customers and the broader Internet when an issue in the @Cloudflare network impacted the large volume of traffic we rely on.

On Tuesday morning, a Cloudflare outage caused a wide range of services, apps and websites to be down for many users. Website DownDetector showed problems reported by users on X, ChatGPT, Canva, Spotify, League of Legends, Canva, DoorDash, Cloud, Uber, and YouTube. Even Grindr went down temporarily. (Disclosure: DownDetector is owned by Ziff Davis, Mashable’s parent company.)
In a statement emailed to Mashable on Tuesday morning, Cloudflare said the problem was caused by a crash in a software system that handles traffic for many of its customers.
“To be clear, there is no evidence that this was the result of an attack or was caused by malicious activity,” the statement said. “We expect some Cloudflare services to be disrupted for a short time as traffic naturally increases after the incident, but we expect all services to return to normal within the next few hours. A detailed statement will be posted on blog.cloudflare.com soon. Given the importance of Cloudflare’s services, any outage is unacceptable. We apologize to our customers, and the Internet in general, for disappointing you today. We will learn from today’s incident and improve.”
If this internet outage sounds familiar, that’s because it is the third major outage in 2025. Just last month, we reported on a widespread Amazon Web Services outage. And before that, the Google Cloud Platform outage had also shut down a large part of the internet.
