Issues with the infrastructure provider caused outages across popular websites worldwide

Major websites such as X and ChatGPT temporarily stopped working due to an outage at Internet infrastructure provider Cloudflare on Tuesday. A popular tool for checking whether a site is down, downdetector.com, has also been affected.

In a message on its status page just before noon UTC, the company said that it “is experiencing an internal service degradation,” and investigating the issue.

Cloudflare’s servers act as “reverse proxy,” routing internet traffic through its network to protect against potential cyberthreats to its customers. It protects nearly a fifth of all sites around the world.

Major websites that use its protection have faced intermittent outages.

Last month, a major outage at Amazon Web Services (AWS) caused widespread disruptions to online services. A single outage can affect millions of users.
