Richard Demongeot — the operator whose measurements these tools reflect
Tools built from real measurement
The instruments on ntp-tester.eu — jitter analysis, live offset, latency benchmark — measure the same quantities Richard Demongeot watches every day operating public time servers. When you read here why offset, jitter and latency matter, it is from the perspective of someone who keeps a Stratum 1 source disciplined and a pool of servers healthy.
NTP track record
- 20+ years in NTP — NTP Pool participant since 2005 (ntppool.org/a/rdem-systems).
- Stratum 1 from GNSS — a GNSS-disciplined reference, measured continuously for offset and stability.
- Authenticated time — public servers supporting NTS (RFC 8915) over TLS.
- Operates on AS206014, with infrastructure in Equinix Paris — real network paths, real latency, real jitter.
Systems & networks background (mini-CV)
- 18 years across software development, databases, UNIX/Linux administration, networks and VoIP.
- Independent consultant since 2007; founded RDEM Systems (SASU) in 2016.
- Proxmox VE virtualization, externalised immutable backup (Nimbus Backup) and 24/7 managed services.
