How Project Shield Stopped a 6.3 Tbps DDoS Attack Against KrebsOnSecurity

When investigative journalist Brian Krebs was targeted by one of the largest DDoS attacks to date at a staggering 6.3 Tbps, his site, KrebsOnSecurity, remained online without interruption.

This was possible thanks to Project Shield, a free Google service that helps defend at-risk websites against DDoS attacks. Following a massive 2016 attack that took his site offline for days, Krebs enrolled in Project Shield. In May, that protection was put to the ultimate test.

The new blog post details how Project Shield, built on Google Cloud’s infrastructure including Cloud Load Balancing and Cloud Armor, automatically filtered the 585 million packets-per-second attack instantly at the network edge.
