NTP and NTS: ntp.gnpk.zip

Gavin Phratsachack · operator, AS218248 · Minnesota, USA - hosted in Düsseldorf, Germany

ntp.gnpk.zip is my NTP server: a dual-stack NTP Pool server with NTS, running chrony on the same VPS as the rest of AS218248. It holds a perfect 20/20 score on the NTP Pool, and it has served over 36 million NTP requests.

Why this exists

NTP keeps my own time accurate — every service on the box, from DNSSEC signing to mail, depends on a correct clock. And the server is part of the NTP Pool, so it keeps other servers’ time accurate too: anyone whose client picks this server gets time from it. Accurate time is one of those things the internet quietly depends on, and running a pool server is a small way to give back.

The setup

NTS is Network Time Security: it authenticates the time exchange, so a client can be sure the time it receives actually came from this server and was not tampered with in transit. The server was verified working, and it was part of the HE IPv6 Certification — Guru, earned Nov 2, 2026.

How much it serves

The server holds a perfect 20/20 score on the NTP Pool — the pool’s own measure of reliability, and a strong signal that the server is well-run.

From chronyc serverstats, Nov 11, 2026 (cumulative since chronyd started — no timeframe is claimed here):

Over 36 million NTP requests served, with none dropped. The timestamp span in serverstats is 88,118 seconds (about 24.5 hours) — the daemon has been holding timestamps steadily for over a day.
