Networking Tech with Fexingo: Internet Infrastructure, Routing, and Network Engineering episodes

  • How BGP Routes the Internet and Why It Matters

    In this episode of Networking Tech with Fexingo, Lucas and Luna dive into the Border Gateway Protocol (BGP) — the glue that routes data across the internet. They explain how BGP works, why it's vulnerable to hijacks (like the 2018 Amazon DNS heist), and how engineers are securing it with RPKI and MANRS. You'll learn why BGP isn't about finding the fastest route, but the only route, and how a single misconfiguration can knock whole countries offline. No jargon overload — just a clear, practical look at the protocol that makes the internet work, and what happens when it breaks.

  • How A Single Fiber Optic Cable Connects Global Finance

    In the premiere episode of Networking Tech with Fexingo, Lucas and Luna anchor on a single concrete example: the transatlantic fiber optic cable that carries trillions of dollars in financial data every day. They trace the route from a trading desk in New York to a data center in London, explaining the network engineering decisions that determine latency, reliability, and security. Lucas breaks down how routing protocols like BGP handle traffic across continents, why undersea cable paths matter for high-frequency trading, and what happens when a cable gets cut. The conversation establishes the show's focus on the physical and logical infrastructure that powers the internet, without hype or oversimplification. Listeners come away understanding one specific link in the global network and why it matters.

About Networking Tech with Fexingo: Internet Infrastructure, Routing, and Network Engineering

From the publisher's feed

Lucas and Luna break down the invisible skeleton of the internet: the routers, protocols, and physical cables that move packets across continents. Each episode opens with a recent network outage, a peering dispute, or a routing-table anomaly — then traces the engineering decisions and business incentives behind it. Lucas maps the technical architecture (BGP, MPLS, IXPs), while Luna pushes on the economics: who pays for undersea cables, why ISPs throttle certain traffic, and how network neutrality shapes startup access. They analyze real incidents — AWS’s Tokyo region failure, a Level 3 vs. Cogent peering war, or the latency impact of a new data-center route — and explain what network engineers actually debate in NANOG meetings. This is not a ‘how the internet works’ primer; it’s the layer-3 view for professionals who manage, build, or invest in network infrastructure. Expect granular discussions of dark fiber, CDN caching strategies, and the politics of IP address allocation. By the end, you’ll see the internet as a finite, fragile, and fiercely competitive topology — and understand why a single undersea cable cut can reset stock prices.
