Series
A three-part series exploring how the internet works — from packet flow in local networks to ISP operations and the global routing system (BGP). Real-world cases reveal both the resilience and fragility of the internet.

Autonomous System The internet isn't a single, monolithic cloud. It’s a massive, interconnected patchwork of thousands of independent networks, and the most fundamental building block of this global structure is the Autonomous System (AS). Think of a...
