Mitigating a 754 Million PPS DDoS Attack Automatically

What this post added

This post details the automatic mitigation of a 754 million PPS DDoS attack using Cloudflare's Gatebot and dosd systems. It explains the attack vectors (SYN floods, ACK floods, SYN-ACK floods) and the distinction between bit-intensive, packet-intensive, and request-intensive DDoS attacks. It highlights the use of BGP Anycast for global traffic distribution, kernel-level packet dropping for efficiency, and L4 load balancing with Unimog to handle massive packet rates without manual intervention.
