Diagnostics written by someone who runs this in production

The troubleshooting guides on check-ntp.net — stratum 16, reach 0, false tickers, daemon issues, Windows/W32Time — come from day-to-day operations, not theory. They are written by a working systems & networks architect who runs chrony, ntpd and w32tm on production hosts and operates an autonomous network.

NTP track record

• 20+ years in NTP — NTP Pool participant since 2005 (ntppool.org/a/rdem-systems).
