On November 18, 2025, at approximately 11:30 UTC, Cisco ThousandEyes began observing a global outage affecting cloud and CDN provider Cloudflare, impacting multiple Internet services including X, OpenAI, and Anthropic. While network paths to Cloudflare's front-end infrastructure appeared clear of any elevated latency or packet loss, Cisco ThousandEyes observed a number of timeouts and HTTP 5XX server errors, which is indicative of a backend services issue. While Cloudflare has confirmed they are implementing remediation, the outage is still ongoing.
