Resources · Network Wiki
Plain-English explainers on the protocols and ideas that decide whether a network is healthy — what they are, why they matter to the business, and what good looks like.
Foundations
Three words that get used interchangeably but mean very different things — and why the difference decides how fast you resolve incidents.
A working model of your network you can question, diff, and simulate against — so you can understand a change before you make it.
Routing
What BGP is, why it decides the path your traffic takes, and why changes to it are the hidden cause of so many outages.
How an accidental or malicious BGP announcement can reroute or black-hole traffic across the internet — and why they're so hard to spot.
The low-grade routing churn that quietly degrades a network long before it fully breaks — and why 'it's slow sometimes' is so hard to catch.
Segmentation
How one physical network carries many isolated ones — the basis of multi-tenant services, and a control you're increasingly required to prove.
Keeping operational technology separate from corporate IT — a safety-critical boundary that regulators now expect you to prove continuously.
