Summary

On February 10th, CloudFlare experienced a massive DDoS attack with nearly 400Gbps of NTP attack traffic hitting their network. They were not the only ones affected; OVH reported a similar-sized attack around the same time. After the attack, they published a list of networks involved in hopes that they would fix the problem. The results have been encouraging: more than 75% of the vulnerable servers are now no longer vulnerable after just over a week and a half. Network administrators worldwide have taken notice and are closing down vulnerable NTP servers to prevent future attacks.
