Welcome Back to the Survival Networking Series

Hey! This series, Survival Networking, explores what it really takes to build and operate global-scale networks that survive multi-terabit failures, software bugs, policy misfires, and everything in between.

If you're just joining, I recommend starting with the first two installments:

  • Survival Networking: What I Learned About Resilience at Scale from FAANG. We unpacked the illusion of HA and showed why survivability starts with systemic thinking.

  • Survival Networking: Resilience at Scale – Part 2. We explored how hyperscalers constrain failure domains, re-route at scale, and validate intent before change.

Today’s post delves into real-world global failover strategies, the engines that simulate intent, and the Git-backed pipelines that enforce safety by design, not by accident.

Let’s keep going.
