Cloudflare said it has largely resolved an outage that rippled across the internet early Tuesday, disrupting ChatGPT, League of Legends, New Jersey Transit and more. By 10:40 a.m. EST, engineers were still mitigating lingering issues and monitoring. X, Shopify, Dropbox, Coinbase and Moody’s were among those hit; Moody’s displayed Error Code 500 directing users to Cloudflare. New York City reported some services affected, and France’s SNCF warned schedules may be unavailable. An expert noted Cloudflare’s role as a content delivery network for roughly 20% of websites, amplifying the impact when it fails.
