Web infrastructure company Cloudflare on Monday disclosed that it thwarted a record-breaking distributed denial-of-service attack that peaked at over 71 million requests per second.

"The majority of attacks peaked in the ballpark of 50-70 million requests per second with the largest exceeding 71 million," the company said, calling it a "Hyper-volumetric" DDoS attack.

It's also the largest HTTP DDoS attack reported to date, more than 35% higher than the previous 46 million RPS DDoS attack that Google Cloud mitigated in June 2022.

HTTP attacks of this kind are designed to send a tsunami of HTTP requests toward a target website, typically in order of magnitude higher than what the website can handle, with the goal of rendering it inaccessible.

"Given a sufficiently high amount of requests, the website's server will not be able to process all of the attack requests along with the legitimate user requests," Cloudflare said.

The development comes as the size, sophistication, and frequency of DDoS attacks are on the rise, with the company recording a 79% spike in HTTP DDoS attacks year-over-year in the final quarter of 2022.
