Technical Details Behind a 400Gbps NTP Amplification DDoS Attack 12 years ago
All NTP seriousness aside, this new "record-breaking" DDoS attack was only possible because CloudFlare -- after the Spamhaus attack -- upgraded and expanded their network endpoints all over the world. When the next attack hits and they have again upgraded their connections with 100Gb/s combined, they'll be able to say that there was again a new record, this time it was 500Gb/s.
