There are global outages for several major websites after internet infrastructure firm CloudFlare says it is trying to fix an issue that has caused serious disruptions. – Nov 18, 2025

A technical issue that hit internet infrastructure firm Cloudflare appears to be mostly resolved after sending a ripple effect across parts of the internet Tuesday morning with multiple global outages reported.

Global News received a response from Cloudflare confirming how the outage occurred.

“The root cause of the outage was a configuration file that is automatically generated to manage threat traffic. The file grew beyond an expected size of entries and triggered a crash in the software system that handles traffic for a number of Cloudflare’s services,” said Cloudflare in an emailed response to Global News.
