San Francisco, November 18, 2025: Cloudflare suffered a significant service disruption on Tuesday, causing widespread outages across multiple platforms, including thousands of user reports from the social media site X, according to the company’s official status page.
The internet infrastructure and security provider experienced what it described as “internal service degradation,” resulting in intermittent failures across several of its core services. The disruption also briefly affected third-party monitoring service Down Detector.
Users attempting to access websites routed through Cloudflare were met with internal server error messages and were advised to try again after a few minutes.
Cloudflare acknowledged the issue early on, stating it was investigating “widespread 500 errors,” along with failures in its dashboard and APIs. “We are working to understand the full impact and mitigate this problem. More updates to follow shortly,” the company said.
In later updates, Cloudflare reported gradual recovery across its systems but cautioned that users might continue to see elevated error rates as work progressed. “We are seeing services recover, but customers may continue to observe higher-than-normal error rates as we continue remediation efforts,” it noted.
Cybersecurity watchdog NetBlocks confirmed that the disruption appeared global and was not linked to state-imposed internet shutdowns or filtering.
Cloudflare said it would continue issuing updates until all services were fully restored.
