Cloudflare admits major failure after global outage disrupts internet services

By TechWatch PH Staff

Cloudflare acknowledged a major failure in its global network that triggered widespread instability across online services, affecting millions of users and causing what observers described as a chain reaction of outages around the world.

In supporting statements, Cloudflare’s Chief Technology Officer Dane Knecht said the company

“We failed our customers and the broader Internet,” explaining that a latent bug in a service tied to its bot mitigation system began crashing after a routine configuration change.

This internal failure cascaded across the network, leading to extensive service degradation. “This was not an attack,” he clarified on his X (formerly known as Twitter) account.

Knecht said the team restored normal traffic flow at around 14:30 UTC, but the outage also affected Cloudflare’s control plane — including the dashboard and APIs customers use to manage their services. These systems were later brought back online, with Cloudflare continuing to monitor stability.

He added that the disruption and the time it took to resolve were “unacceptable,” and vowed that the company would take all necessary steps to ensure it never happens again.

Knecht added that Cloudflare will release a detailed breakdown “in a couple of hours,” explaining the sequence of failures and the steps being taken to ensure the issue does not happen again.

The November 18 outage marks one of Cloudflare’s most significant service disruptions in recent years, underscoring the heavy dependence of online platforms, businesses, and critical digital infrastructure on the company’s global network.
