Somebody out there was getting hit hard by a distributed denial-of-service (DDoS) attack on Monday, according to multiple reports. And it looks like this one was even harsher than last year’s Spamhaus incident, at the time the biggest known DDoS attack in the history of the internet.

According to Matthew Prince, CEO of anti-DDoS protection outfit CloudFlare:

Prince went on to say the attack was running at over 400Gbps (Spamhaus was around 300Gbps), though confidentiality stopped him from identifying which client was getting hammered. He said the effects were being felt particularly in Europe, with the attack being mostly mitigated but still “big enough it caused problems even off our network, which is super annoying.”
