Cloudflare’s Most Severe Outage Since 2019 Resolved Quickly

Cloudflare experienced a major outage on November 18, 2025, disrupting services including CDN and security features, with the company citing database configuration errors as the cause.

The outage underlines the vulnerability of internet infrastructure, with significant potential impacts on dependent web services, including those in cryptocurrency sectors, though no direct crypto impacts were cited.

Market Stability Amidst Internet Infrastructure Challenge

Cloudflare’s outage was attributed to an incorrect configuration file post-database permission adjustments, initially mistaken for a DDoS attack. Cloudflare quickly rectified this by reverting configuration errors. CEO Matthew Prince issued a public apology, noting: “On behalf of the entire team at Cloudflare, I would like to apologize for the pain we caused the Internet today.”

Changes were swiftly implemented to restore services. Cloudflare now seeks to enhance system resilience through configuration file safeguards and global kill switches to mitigate recurrence. You can find more details in the Cloudflare Outages Archive.
