I am reliably informed by Google Shield that my site krebsonsecurity.com on Monday was the target of the biggest DDoS attack Google has ever had to deal with, clocking in at ~6.3 Tbps. This is not quite a record; apparently, an attack Cloudflare had to deal with in April is the largest known DDoS to date -- at ~6.5 Tbps.
It's been a while since we've seen a big DDoS. For reference, this one was about 10x the size of the Mirai botnet attack that launched a record DDoS against my site in 2016, knocking it offline for nearly 4 days until I got the site behind Google Sheild.
I'll know more in a bit. Below is the CF blog about their April attack.
