How Network Time Protocol Syncs the Internet

What this episode covers

Episode 47 of Networking Tech with Fexingo dives into the overlooked backbone of global synchronization: Network Time Protocol (NTP). Lucas and Luna explore how NTP keeps data centers, financial exchanges, and 5G networks within milliseconds of each other, using a real-world example from the 2025 AWS time-sync incident that caused a 12-minute trading halt on the Nasdaq. They break down the leap-second debate, the coming deprecation of leap seconds by 2035, and why Google, Meta, and Microsoft each run their own NTP stratum strategies. If you've ever wondered how your phone knows what time it is — or why a 200-millisecond clock skew can crash a distributed database — this episode delivers the concrete mechanics. #NetworkTimeProtocol #NTP #LeapSecond #TimeSynchronization #PrecisionTimeProtocol #PTP #Stratum #DataCenter #5G #Nasdaq #AWS #Google #Meta #Microsoft #Technology #InternetInfrastructure #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo
