Cloudflare blocks largest DDoS attack - here's how to protect yourself

Cloudflare just stared down a raging beast: a 7.3 Tbps DDoS attack, like blasting 10,000 HD movies straight through your eyes in a heartbeat. This monster, 99.996% UDP floods, erupted from 122,145 source IPs scattered across 161 countries. Its real claim to fame? Not sheer size, but breakneck speed. In 2025, DDoS attacks skyrocketed 358%, mostly riding the wave of these UDP-fueled network-layer sucker punches.
