Measurement page for ICMP echo RTT from Paris, France, to Amsterdam, Netherlands: 7 ms average, 0% packet loss, stability details from 50 samples.

🇫🇷 Paris, France (PAR) → 🇳🇱 Amsterdam, Netherlands (AMS)

Measurement round: 2026-08-16T04:07:28Z.

In the 2026-08-16T04:07:28Z round, 50 ICMP echo requests from Paris, France, to Amsterdam, Netherlands returned an average RTT of 7 ms, with a minimum of 6.65 ms and a maximum of 8.5 ms. No packets were lost, and jitter was 0.24 ms, so the path remained extremely steady across the 100 ms sampling interval.

The measured path covers a geodesic distance of 430.9 km. Against a fiber-floor estimate of 4.22 ms, the observed average is 1.66 times that floor, a fiber efficiency of 60.3% and a relatively small gap between theoretical distance and actual round-trip time.

This route ranked 2nd among 19 outbound routes. Its standard deviation of 0.33 ms is about 4.7% of the average, slightly above the median variability of 3.28% across the same route set; in absolute terms, however, the route stays within a narrow, loss-free range and remains an ultra-low-latency ICMP path.

Ping Measurement Series

The chart below renders the 50-sample ICMP echo measurement round for this route; an accessible table of every sample is included with the chart.

Ping series: PAR → AMS

50 ICMP echo samples at 100 ms intervals · round 2026-08-16T04:07:28Z · avg 7.0 ± 0.05 ms (SE)

Sample distribution: box = interquartile range (6.8–7.2 ms), median 6.9 ms · whiskers = min–max · diamond = round average · each dot is one measured sample.

How to read this chart

The shaded band spans the measured minimum to maximum RTT of all samples collected up to that point, and the thin line traces the running average. The final position therefore matches the round statistics exactly — the band only widens when a new extreme sample arrives.

The dashed line is the round average, and the shaded band at the bottom is the theoretical fiber-optic floor (4.2 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Paris (48.85341, 2.34880) and Amsterdam (52.37403, 4.88969). It does not disclose either facility address.

Physical Reference	Value

About This Measurement

Published RTT reflects best-case backbone path behavior measured with ICMP echo probes between PoPs. End-user latency also depends on local access networks, congestion, routing policy, and traffic engineering. None of these values is an SLA.

The measurement round behind this page is published as open data under CC BY 4.0 in the Hats Network latency dataset. Per-pair files are available at /opendata/latency/latest/pairs/par-ams.pings.{csv,json,yaml}.
