Why Your NTP Setup Is Probably Drifting
from Linux Server Admin with Fexingo: Sysadmin, Bash, and Server Engineering · host Fexingo
Episode 11 of Linux Server Admin tackles a silent server killer: clock drift. Lucas and Luna explain why even a 50-millisecond offset can break database replication, certificate validation, and distributed consensus. They walk through a real example of a PostgreSQL cluster that failed silently because chrony wasn't configured to poll multiple upstream servers. They compare ntpd vs chronyd vs systemd-timesyncd, show how to check drift with chronyc tracking, and explain why you should never use a single NTP source. A concrete guide for sysadmins who want production-grade time sync. #NTP #ClockDrift #Chrony #SystemdTimesyncd #ServerTime #LinuxSysadmin #PostgreSQL #DatabaseReplication #ProductionServer #TimeSync #Chronyc #DistributedSystems #Technology #Linux #Sysadmin #FexingoBusiness #BusinessPodcast #ServerEngineering Keep every episode free: buymeacoffee.com/fexingo
