Cloudflare Mitigated DDoS Attack of 17.2 Million Request-Per-Second

[engine]

Cloudflare has reported how it detected and mitigated a massive DDoS attack in June.

I can't help but wonder how big the resources are for such attacks, unless they are zombie machines around the globe.

Cloudflare’s autonomous edge DDoS protection systems automatically detected and mitigated a 17.2 million request-per-second (rps) DDoS attack, an attack almost three times larger than any previous one that we're aware of. For perspective on how large this attack was: Cloudflare serves over 25 million HTTP requests per second on average. This refers to the average rate of legitimate traffic in 2021 Q2. So peaking at 17.2 million rps, this attack reached 68% of our Q2 average rps rate of legitimate HTTP traffic.
