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. 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. #InternetInfrastructure #NetworkEngineering #BGP #InternetExchange #Peering #CDN #DDoS #NetworkNeutrality #DataCenters #UnderseaCables #IPAddressing #ISP #FiberNetworks #Latency #NANOG #Technology #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo© 2026 Fexingo.

  • How Link-State Routing Converges After a Fiber Cut

    How Link-State Routing Converges After a Fiber Cut
    2026/06/08
    Episode 39 dives into the mechanics of link-state routing protocols like OSPF and IS-IS when a fiber cut happens. Using the real-world example of a multi-vendor outage in Frankfurt in late 2025, Lucas and Luna walk through the convergence sequence: failure detection, LSA flooding, SPF recalculation, and FIB update. They explain why convergence times vary from milliseconds to seconds depending on technology choices like Bidirectional Forwarding Detection (BFD) and incremental SPF. The episode also covers the trade-off between fast convergence and network stability, including how timer back-off mechanisms prevent micro-loop storms. A concrete look at what happens inside routers when a trench gets dug in the wrong place. #LinkStateRouting #OSPF #ISIS #BFD #SPF #Convergence #FiberCut #NetworkEngineering #RouteRedistribution #MicroLoop #FIB #LSA #FrankfurtOutage #Technology #FexingoBusiness #BusinessPodcast #InternetInfrastructure #RoutingProtocols Keep every episode free: buymeacoffee.com/fexingo

  • How Zero Touch Provisioning Automates Network Deployment

    How Zero Touch Provisioning Automates Network Deployment
    2026/06/08
    Episode 38 of Networking Tech with Fexingo explores Zero Touch Provisioning (ZTP), the automation technology that lets network devices configure themselves without manual intervention. Lucas and Luna break down how ZTP works using DHCP and bootstrap servers, why it's essential for large-scale data center deployments, and how it reduces human error. They discuss real-world adoption by cloud providers and enterprises, compare ZTP to legacy manual provisioning, and touch on security considerations like authenticated bootstrapping. The episode also covers how ZTP fits into the broader network automation ecosystem alongside tools like Ansible and Cisco DNA Center. A must-listen for network engineers and anyone curious about how modern networks are built at scale. #ZeroTouchProvisioning #NetworkAutomation #DHCP #BootstrapServer #DataCenter #Cisco #Ansible #CiscoDNACenter #NetworkEngineering #Technology #Automation #CloudNetworking #EnterpriseNetworking #ConfigurationManagement #NetworkDeployment #FexingoBusiness #BusinessPodcast #NetworkingTech Keep every episode free: buymeacoffee.com/fexingo

  • How Network Configuration Drift Causes Outages

    How Network Configuration Drift Causes Outages
    2026/06/07
    Episode 37 of Networking Tech with Fexingo. Lucas and Luna explore network configuration drift—the silent accumulation of undocumented changes that leads to unexpected outages. They walk through a real 2025 incident where a single uncommitted 'no shut' command on a core router caused a 47-minute outage for a major European bank. They explain what drift is, how it happens (manual patches, emergency changes, OS upgrades), and why traditional auditing tools catch only 60% of discrepancies. They also discuss emerging solutions: intent-based networking, automated backup validation, and immutable infrastructure. The episode closes with a practical takeaway: any network engineer can start a simple 'golden config' diff process this week without buying new software. #NetworkConfigurationDrift #NetworkOutages #RouterConfig #IntentBasedNetworking #GoldenConfig #NetworkAutomation #NetworkEngineering #NetworkReliability #TechIncident #EuropeanBank #ConfigurationManagement #ImmutableInfrastructure #NetworkAudit #CLI #Ansible #Technology #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo
