Cloudflare Outage Disrupts Major Online Services

On November 18, 2025, a significant outage at Cloudflare, a major internet infrastructure provider, disrupted numerous online services worldwide. Users experienced difficulties accessing platforms such as X (formerly Twitter), ChatGPT, Spotify, YouTube, and Uber.

Cloudflare's co-founder and CEO, Matthew Prince, attributed the disruption to an internal configuration error. A routine update to the company's Bot Management system inadvertently generated an oversized feature file, which exceeded system limits and caused widespread failures across the network.

The outage began around 11:20 UTC and lasted approximately five hours. Cloudflare's engineering team identified the issue and implemented a fix, restoring services by early afternoon.

This incident underscores the critical role of infrastructure providers like Cloudflare in maintaining internet stability. The company has committed to reviewing its processes to prevent similar occurrences in the future.
