Cloudflare is down, as websites are crashing with a 500 Internal Server Error. Cloudflare has confirmed that it’s investigating the reports.
Cloudflare, a service that many websites use to stay fast and secure, is currently facing problems.
Because of this, people visiting some websites are seeing a “500 Internal Server Error” message instead of the normal page.
A 500 error usually means something went wrong on the server side, not on the user’s device or internet connection.
In an update to its status page, Cloudflare states that it’s investigating issues with the Cloudflare Dashboard and related APIs.
“Customers using the Dashboard / Cloudflare APIs are impacted as requests might fail and/or errors may be displayed,” the company noted.
Cloudflare says it has implemented a fix, and websites should start coming back online soon.
Cloudflare says React2Shell patch deployment caused the outage
Claudflare has shared more details in another update to its documentation and promised to publish a detailed report soon.
According to the company, it made a change to Cloudflare’s Web Application Firewall to patch an industry-wide vulnerability (React2Shell) affecting React Server Components.
The patch caused issues with Cloudflare, which crashed millions of websites, including Cloudflare’s own dashboard.
“This was not an attack; the change was deployed by our team to help mitigate the industry-wide vulnerability disclosed this week in React Server Components,” the company explained.
Update 1: All websites have been fully restored as of 8 AM ET.
