On November 18, 2025, at 11:48 UTC, Cloudflare officially confirmed that its global network is experiencing widespread issues that may affect millions of users and businesses worldwide. The company posted an “Investigating” notice on its status page, acknowledging that an ongoing problem is impacting multiple customers across different regions and services.

Cloudflare, one of the largest and most widely used internet infrastructure providers, powers a significant portion of global web traffic, including websites, APIs, SaaS platforms, ecommerce systems, and security services. When Cloudflare’s network encounters disruptions, the ripple effect is felt across the entire internet.

In the early hours of the day, users began reporting timeouts, connection failures, and slow-loading websites. Downdetector charts showed a sudden and massive spike in error reports, indicating a large-scale outage. Platforms relying on Cloudflare’s CDN, DNS, firewall, and reverse-proxy layers have experienced partial or complete unavailability.

The company has not yet revealed the exact cause of the incident. Past Cloudflare outages have been attributed to routing misconfigurations, software updates gone wrong, overloaded network nodes, or issues affecting backbone connectivity. What makes today’s incident significant is the global impact, suggesting the problem may be tied to a core system within Cloudflare’s network.

Cloudflare stated that further details will be provided as more information becomes available. For now, engineers are actively investigating the root cause and working to restore normal service.

Businesses and developers relying on Cloudflare for uptime and security are advised to monitor the official status page closely. Until the investigation concludes, users may continue to experience instability, elevated error rates, or intermittent downtime.

As Cloudflare remains one of the most critical pillars of today’s internet infrastructure, any disruption—even short-lived—can cause widespread performance issues across the web. More updates are expected soon as the company works to diagnose and address the situation.
