ICMP RTT measurements from Paris, France to Amsterdam, Netherlands: 50 ping samples, 7 ms average, zero loss, and stability metrics for this route.

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

Measurement round: 2026-08-15T04:03:13Z.

For the 2026-08-15T04:03:13Z ICMP echo RTT round, the Paris-to-Amsterdam path returned an average round-trip time of 7ms across 50 samples, with a minimum of 6.78ms and a maximum of 7.81ms. The 0.23ms standard deviation and 0.17ms jitter show tightly clustered samples, and every probe was answered, so packet loss is 0%.

Against the 4.22ms fiber floor implied by the 430.9km geodesic separation, the 7ms average is 1.66 times the floor, corresponding to a 60.3% fiber efficiency. The route sits in the ultra-low latency tier for this measurement window.

This route ranked 1st of 19 outbound routes from Paris for average latency. The network-wide median standard-deviation-to-average ratio is 3.08%, and this route's ratio of 0.23ms on 7ms is about 3.3%, close to that median. With zero loss and a maximum-minimum spread of just over 1ms, this Paris-to-Amsterdam measurement offers a dependable ultra-low-latency reference.

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 2026-08-15T04:03:13Z · avg 7.0 ± 0.03 ms (SE)

Sample distribution: box = interquartile range (6.8–7.1 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
WGS-84 geodesic distance	430.9 km
Vacuum RTT floor	2.87 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	4.22 ms
Low-latency fiber material floor	4.2 ms
Engineering floor (5% path allowance)	4.43 ms
Research 1.33× mapped-fiber reference	5.61 ms
Estimated unamplified path loss	90.5 dB
Transparent optical spans / inline amplifiers	6 / 5
Published RTT inflation over fiber floor	1.66×

Attenuation is used to estimate the number of 80 km optical spans; it does not directly slow light. See the full theoretical fiber latency, GeoNames, attenuation, and amplifier methodology.

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.
