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…","last_synced_at":"2026-07-18T22:19:10.157593+00:00","page_url":"https://stenobird.com/podcast/networking-tech-with-fexingo-internet-infrastructure-routing-and-network-engineering-7871928"},"episode":{"title":"How Network Observability with eBPF Works","slug":"how-network-observability-with-ebpf-works","published_at":"2026-06-27T10:09:07+00:00","page_url":"https://stenobird.com/podcast/networking-tech-with-fexingo-internet-infrastructure-routing-and-network-engineering-7871928/how-network-observability-with-ebpf-works","show_page_url":"https://stenobird.com/podcast/networking-tech-with-fexingo-internet-infrastructure-routing-and-network-engineering-7871928","url":"https://audio.fexingo.com/business/networking-tech/episode-0076.mp3","audio_url":"https://audio.fexingo.com/business/networking-tech/episode-0076.mp3","summary":"Episode 76 of Networking Tech with Fexingo dives into eBPF, the kernel technology that gives network engineers unprecedented visibility into traffic flows without changing application code. Lucas and Luna walk through the network observability startup Cilium and its eBPF-based approach to service mesh and security policies at scale. They discuss how companies like ByteDance and Capital One use eBPF to reduce latency by 40% and cut CPU overhead for network monitoring. The hosts also explore the trade-offs: a steep learning curve and potential kernel stability risks. With practical examples from production deployments, this episode explains why eBPF is the hottest tool in cloud-native networking since Kubernetes. #eBPF #Cilium #NetworkObservability #KernelProgramming #CloudNative #Kubernetes #ServiceMesh #ByteDance #CapitalOne #LinuxKernel #BPF #NetworkPerformance #Latency #SecurityPolicies #Technology #NetworkEngineering #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo","meta_description":"Episode 76 of Networking Tech with Fexingo dives into eBPF, the kernel technology that gives network engineers unprecedented visibility into traffic flows…","key_points":[],"chapters":[],"topics":[],"duration_seconds":539,"processing_state":"not_requested","actions":[{"name":"request_transcript","method":"POST","url":"https://stenobird.com/v1/public/podcasts/networking-tech-with-fexingo-internet-infrastructure-routing-and-network-engineering-7871928/episodes/how-network-observability-with-ebpf-works/transcription-requests","description":"Idempotently request low-priority transcript generation for this episode."},{"name":"read_markdown","method":"GET","url":"https://stenobird.com/podcast/networking-tech-with-fexingo-internet-infrastructure-routing-and-network-engineering-7871928/how-network-observability-with-ebpf-works.md","description":"Read the agent-friendly Markdown representation of this episode resource."}]}}
