Honest question: is it not best practice to have an isolated, dedicated management network? I can’t for the life of me understand why a misconfig on the production network should hamper access through the admin network. Unless on Google’s scale it’s not the proper way to design and operate a network ?
- remus 7y agoPresumably it's a trade off of complexity against redundancy, and at the scale that google's datacenters run the complexity is too high to make it worthwhile.

- SpicyLemonZest 7y agoOn Google's scale, the networks are themselves production systems. So the question they face isn't whether to keep a single isolated network, but how long it's worth keeping the recursion going.
