Cloudflare admitted to failures during a major outage on November 18, 2025, caused by an unusual traffic spike that affected thousands of websites globally. The outage disrupted access to several high-profile platforms, including X and ChatGPT. Restoration efforts are still ongoing, with partial services being resumed as Cloudflare works to fully restore its infrastructure. The company has promised a post-incident analysis to determine the root cause of the traffic surge, while users await complete resolution of the service disruption.
