Cloudflare has announced that it successfully blocked a massive DDoS attack that peaked at 22.2 Tbps. This attack nearly doubles the size of the previous largest recorded attack, which was a staggering 11.5 Tbps. Cloudflare stated it autonomously mitigated attacks of this scale, which reached a peak of 10.6 billion packets per second (Bpps). The attack reportedly lasted for just 40 seconds.

“Cloudflare just autonomously blocked hyper-volumetric DDoS attacks twice as large as anything seen on the Internet before — peaking at 22.2 Tbps & 10.6 Bpps. Can your mitigation provider’s scrubbing capacity handle that scale?”
(Translated: Cloudflare successfully handled an unprecedented DDoS attack, exhibiting their capability in cybersecurity.)

As investigations continue, more details on the attack mechanics are expected to be released.
