In mid-May 2025, Cloudflare blocked the largest DDoS attack ever recorded: 7.3 terabits per second (Tbps).

That’s the equivalent of flooding the internet with over 9,350 HD movies or streaming 7,480 hours of uninterrupted high-definition video (nearly a year’s worth of back-to-back TV binge-watching) in just 45 seconds.
