How a BGP Leak Broke the Internet for Four Hours in 2025

When a small regional ISP in Kentucky misconfigured its BGP route advertisements in March 2025, it took down major websites across North America for nearly four hours. Lucas and Luna dissect the anatomy of that leak — how a single router at a provider called NetRural accidentally advertised 20,000 more-specific prefixes, causing Amazon, Google, and Cloudflare to reroute traffic through congested paths. They explain why BGP still trusts every neighbor by default, why RPKI filters couldn't stop the leak quickly enough, and what operators are doing now to prevent the next one. A concrete lesson in how fragile the internet's routing fabric can be — and what it will take to harden it. #BGP #BGPLeak #InternetInfrastructure #NetworkEngineering #NetRural #RouteLeak #RPKI #InternetResilience #NetworkOutage #BorderGatewayProtocol #RoutingSecurity #Technology #NetworkProtocols #ISPOutage #2025Outage #FexingoBusiness #BusinessPodcast #TechPodcast Keep every episode free: buymeacoffee.com/fexingo
