On November 18, 2025, a significant outage at Cloudflare, a major web infrastructure provider, led to widespread disruptions across numerous online platforms. Users globally reported difficulties accessing services such as X (formerly Twitter), ChatGPT, Canva, and Grindr. The incident began around 6:40 a.m. ET, with Cloudflare identifying an internal service degradation. By 8:00 a.m. ET, reports of issues had decreased, but some users continued to experience problems.

Cloudflare attributed the disruption to an unusual spike in traffic at 11:20 UTC, which resulted in network errors affecting traffic passing through its network. The company stated, “We are all hands on deck to make sure all traffic is served without errors.” ([reuters.com](https://www.reuters.com/business/elon-musks-x-down-thousands-us-users-downdetector-shows-2025-11-18/?utm_source=openai))
