Recently, Cloudflare automatically detected and mitigated a 17.2 million request-per-second (rps) DDoS attack, an attack almost three times larger than previously ever reported.
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 - therefore, peaking at 17.2 million rps, this attack reached 68% of our Q2 average rps rate of legitimate HTTP traffic, Cloudflare says.
