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

How Internet Exchange Points Shape the Web 22.05.2026 11:16
In this episode of Networking Tech with Fexingo, Lucas and Luna dive into the hidden backbone of the internet: Internet Exchange Points (IXPs). They explore how IXPs like DE-CIX in Frankfurt and AMS-IX in Amsterdam reduce latency, cut costs, and keep data flowing efficiently. Using real-world examples, Lucas explains how a single IXP can handle over 10 terabits per second of traffic and why peerin...
Why DNS Is the Internet's Quietest Bottleneck 21.05.2026 9:14
Episode 3 of Networking Tech with Fexingo dives into the Domain Name System—the phonebook of the internet that translates domain names into IP addresses. Lucas and Luna unpack how a single DNS query can travel through up to eight recursive resolvers, what happened when Dyn DNS was hit by the 2016 Mirai botnet attack, and why a 100-millisecond delay in DNS response can cost an e-commerce site milli...
How BGP Routes the Internet and Why It Matters 21.05.2026 8:51
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 singl...
How A Single Fiber Optic Cable Connects Global Finance 19.05.2026 10:09
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 do...
