Cloudflare is currently experiencing a major outage that is causing many websites to crash with a “500 Internal Server Error.” The company has confirmed that it is investigating the issue.
Cloudflare is a service used by many websites to improve speed and security. Due to the ongoing problems, visitors to some sites are seeing error messages instead of the normal content.
A 500 Internal Server Error usually indicates that something has gone wrong on the server side, rather than with the user’s device or internet connection.
Impact on Cloudflare Dashboard and APIs
In a status update, Cloudflare reported that it is investigating problems affecting the Cloudflare Dashboard and related APIs.
According to the company, customers using the Dashboard or Cloudflare APIs may experience failed requests or see error messages.
Cloudflare says it has deployed a fix, and affected websites are expected to start coming back online gradually.
Cloudflare links outage to React2Shell patch
Cloudflare has shared additional details in a further update and has promised to release a full incident report soon.
The company explained that it recently made a change to its Web Application Firewall to address an industry-wide vulnerability known as React2Shell, which affects React Server Components.
This patch triggered issues within Cloudflare’s systems and caused millions of websites to crash, including Cloudflare’s own dashboard.
The company emphasized that this was not the result of an attack. Instead, the outage was caused by an internal configuration change deployed to mitigate the newly disclosed vulnerability in React Server Components.
Services restored
Cloudflare reports that all affected websites were fully restored as of 8:00 AM ET (approximately 8:00 AM ET / 2:00 PM CET / 6:30 PM IST).
