Just a small point but google.com and YouTube do not run on the same infra as what you see on GCP, especially if you use GKE etc...

It's trivial to see because when GCP is down somehow Google and Gmail keep working.

We do not use GKE.

The Google infra that we do use in this hot path (GFE via Google Global External Load Balancers, and Colossus via Google Cloud Storage) is the same infra that powers serving static assets for Google internal services.
