For what it is worth: My GCP-hosted site (https://cloud.sagemath.com) was hit by a DDoS attack in April (a WordPress amplification attack), which was about 5GB/s at peak time. The GCP network had no problem handling the traffic, but the Linux network stack in my cluster of GCE VMs -- which were running nginx -- simply couldn't handle the load. I now use CloudFlare.

Sorry for your troubles! Why'd you let it through, Bill? (Also, did Support help you out with this or not? You can email me your case number if so).

Disclosure: I work on Google Cloud.

It sounds like too much abussive traffic reached the VM. I guess Google doesn't have a similar product as CloudFlare for normal sites that can throw up captchas, enable caching, etc. in response to an attack.
