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 en

How DNS Caching Speeds Up Your Web Browsing
Oct 3, 202611 minS5
We dive into the often-overlooked hero of internet performance: DNS caching. While most people focus on fiber optic cables or server hardware, the Domain Name System acts as the internet’s phonebook, translating human-readable domain names into IP addresses. In this episode, we explore how recursive resolvers like Google Public DNS and Cloudflare work to minimize latency through intelligent caching strategies. We break down TTL values, the difference between local and global caches, and why your browser’s cache matters just as much as your ISP’s. If you have ever wondered why some websites load instantly while others stutter, the answer often lies in how efficiently your device is storing and retrieving these critical mapping records. We also look at recent shifts in privacy laws affecting DNS logging and what that means for your digital footprint. #DNSCaching #InternetInfrastructure #NetworkEngineering #TechNews #WebPerformance #Cloudflare #GooglePublicDNS #LatencyReduction #CyberSecurity #DigitalPrivacy #ITProfessional #SystemAdministration #FexingoBusiness #BusinessPodcast #LucasAndLuna #TechTalk #OnlineSafety #DataOptimization Keep every episode free: buymeacoffee.com/fexingo
We explore how the silent, private contracts between internet backbone providers actually determine your connection speed and reliability. Lucas and Luna break down the economics of peering disputes, using a specific recent outage to show how business decisions, not technical failures, cause latency spikes. You will learn why some networks prioritize traffic over others and what this means for the future of open internet access. #InternetInfrastructure #BGPProtocols #NetworkEngineering #TechBusiness #FexingoBusiness #BusinessPodcast #ISPContracts #DataRouting #TelecomIndustry #DigitalEconomics #CloudComputing #NetworkLatency #InternetGovernance #PeeringDisputes #TechPolicy #LucasAndLuna #NetworkSecurity #FutureOfInternet Keep every episode free: buymeacoffee.com/fexingo
Every packet of data traveling across the internet follows a path determined by complex routing protocols, but most users never think about why their connection feels slow or unstable. In this episode, Lucas and Luna dive into Border Gateway Protocol, or BGP, and how it manages the global routing table that directs traffic between different networks. They explore a recent case study involving a major cloud provider’s misconfiguration that led to widespread outages, highlighting the fragility of our interconnected digital infrastructure. The hosts explain how ISPs negotiate peering agreements, the concept of transit versus settlement-free connections, and why some routes are preferred over others based on policy rather than just speed. Listeners will learn how a single erroneous route announcement can cascade across continents, affecting everything from stock trading to video calls. This deep dive into network engineering reveals the hidden architecture that keeps the modern economy online. #BGPRouting #InternetInfrastructure #NetworkEngineering #CloudOutages #ISPPeering #DataPaths #TechExplained #DigitalEconomy #CyberSecurity #LatencyIssues #FexingoBusiness #BusinessPodcast #LucasAndLuna #TechNews #InternetProtocol #GlobalNetworking #SystemArchitecture #TechCareers Keep every episode free: buymeacoffee.com/fexingo
We dig into the often-overlooked mechanics of interior gateway protocols and how routers within a single network coordinate to find the fastest path for your data. Using a concrete example from a major cloud provider's internal backbone, we explore why BGP gets all the fame while OSPF and IS-IS do the heavy lifting. We look at the specific trade-offs between convergence speed and administrative overhead in enterprise networks today. #NetworkEngineering #InteriorGatewayProtocols #OSPF #IS-IS #RoutingTables #CloudInfrastructure #DataCenters #BGPVsIGP #NetworkConvergence #PacketSwitching #TechDeepDive #InternetArchitecture #SysAdminLife #DigitalInfrastructure #FexingoBusiness #BusinessPodcast #TechnologyNews #CyberSecurity Keep every episode free: buymeacoffee.com/fexingo
We explore the counterintuitive economics of network redundancy. Why do companies pay millions for backup paths that sit idle ninety-nine percent of the time? Lucas and Luna break down the specific trade-offs between capital expenditure and operational risk, using a major fiber-optic backbone failure as our anchor. You will learn why 'always-on' backups are actually the most expensive line item in many CTOs' budgets, and how new software-defined networking tools are changing the math on disaster recovery without breaking the bank. #NetworkEngineering #InternetInfrastructure #FexingoBusiness #BusinessPodcast #TechEconomics #RedundancyPlanning #CTOInsights #FiberOptics #DisasterRecovery #CapExVsOpEx #SoftwareDefinedNetworking #RiskManagement #DataCenterOps #NetworkResilience #ITLeadership #TechStrategy #InternetRouting #BusinessContinuity Keep every episode free: buymeacoffee.com/fexingo
Every question we get asked before someone starts their trial.
If you have a concern about deliverability, AI quality, data privacy, or whether this will actually work for your specific situation, it's probably answered below.
What is the difference between Founder Solo and Founder Pro?
Founder Solo gives you 50 AI pitches per month using the credit model (Standard pitches cost 1 credit, Enriched pitches cost 2). Founder Pro raises that to 200 credits per month and adds full Booking Probability access, unlimited Magic Match, Apollo enrichment credits, and data export capabilities. Both plans use the same credit system, so you can stretch your monthly budget further by using Standard-mode drafting.
How do agency tiers work?
Agency tiers have no base fee. You pay per managed client and per talent profile. Agency Standard is $199 per client per month; Agency Pro is $399 per client per month. Both add $39 per talent profile per month. Your own team's user seats are always free.
What is a talent profile?
A talent profile represents one person (founder, executive, or spokesperson) you are booking onto podcasts. It includes their bio, topics, headshots, and outreach history. Team plans include 5 profiles; agency plans are pay-as-you-go.
Can I switch plans later?
Yes, at any time. Upgrades take effect immediately; downgrades apply at the end of the current billing period. Contact support if you need help migrating between plan families.
Do you offer a free trial?
Every paid plan includes a 15-day free trial. Your card is saved at signup but you will not be charged until day 16. Cancel any time from your dashboard.
What happens if I cancel?
You keep access until the end of your current billing period. No charges after that. Your data is retained for 30 days in case you reactivate.
Is the 20% annual discount automatic?
Yes. Select Annual on the pricing toggle and the discounted price is applied automatically at checkout. The annual price shown is the full year cost.
What if I have more than 50 profiles or 20 clients?
That is our Enterprise tier. Contact our sales team and we will build a custom plan with volume pricing, a dedicated account manager, and SLA guarantees.
