Cloudflare blocks 15M rps HTTPS DDoS attack

In April 2022, Cloudflare detected and mitigated a massive HTTPS DDoS attack with 15.3 million request-per-second (rps), one of the largest on record. The attack targeted a crypto launchpad customer operating under the Pro plan. It was launched by a botnet consisting of approximately 6,000 unique bots from 112 countries and over 1,300 networks. Interestingly, most of the attack traffic originated from data centers rather than residential ISPs. Cloudflare's autonomous systems automatically detected and mitigated the attack without human intervention. The company offers unlimited and unmetered DDoS protection for its customers to help build a better internet.
