Google has reported that it was successful at blocking the largest layer 7 DDoS attack ever.
On June 1st at 9:45am PT, hackers attempted to shut down one of the company’s Cloud Armor customers with a DDoS attack of 46 million rps (requests-per-second), which Google say is “at least 76% larger than the previously recorded record. Requests began dropping after a few minutes.
“To give a sense of the scale of the attack, that is like receiving all the daily requests to Wikipedia (one of the top 10 trafficked websites in the world) in just 10 seconds,” said the company on it’s Google Cloud blog.

Google Cloud Armor protects services from attacks like these regularly, through early detection by comparing activity to normal traffic patterns via Adaptive Protection, as well as a variety of load-balancing techniques.
Whilst Cloud Armor states that it can take on over a million queries per second, the 46 million of this latest attack proved to be no issue whatsoever.
Google however has confirmed that DDoS attacks are “increasing in frequency and growing in size exponentially.”
“Today’s internet-facing workloads are at constant risk of attack with impacts ranging from degraded performance and user experience for legitimate users, to increased operating and hosting costs, to full unavailability of mission critical workloads.”
