According to capacityglobal, on the evening of November 18, 2025, users in many parts of the world were unable to access websites such as OpenAI and X (formerly Twitter) normally due to a service outage at Cloudflare. Cloudflare confirmed that an abnormal surge in traffic occurred starting at 11:20 UTC, causing network relay errors. Some services have been restored, but users may still encounter error rates higher than normal.
