ICMP RTT measurement results for Marseille, France, to Amsterdam, Netherlands: average latency, jitter, packet loss, and physical reference.

🇫🇷 Marseille, France (MRS) → 🇳🇱 Amsterdam, Netherlands (AMS)

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

ICMP echo measurements in the 2026-08-16T04:07:28Z round put Marseille-to-Amsterdam at an average RTT of 20.3 ms, with a minimum of 19.62 ms and a maximum of 22.75 ms over 50 samples. The route posted zero packet loss and 0.48 ms of jitter, which is why it lands in the 'Ultra-Low' latency tier.

The geodesic distance is about 1,009.9 km, placing the vacuum floor at 6.74 ms and the fiber floor at 9.89 ms. At 20.3 ms, the measured RTT is 2.05 times the fiber floor, or roughly 48.7% fiber efficiency, leaving room for the extra cable length that real networks require between a Mediterranean landing hub and a Northwest European interconnection point.

This route ranked 4th among the 19 outbound routes measured from Marseille in this round, placing it close to the top of the source's latency order. Its standard deviation of 0.64 ms is about 3.15% of the average, slightly below the round-wide median variability of 3.28% across the outbound group.

The practical takeaway is that the Marseille–Amsterdam path is both fast and consistent for a roughly 1,000 km link. With no sample loss and very low jitter, the 20.3 ms average is a representative value rather than a lucky outlier.

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: MRS → AMS

50 ICMP echo samples at 100 ms intervals · round 2026-08-16T04:07:28Z · avg 20.3 ± 0.09 ms (SE)

Sample distribution: box = interquartile range (19.9–20.5 ms), median 20.1 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 (9.9 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Marseille (43.29695, 5.38107) and Amsterdam (52.37403, 4.88969). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	1,009.9 km
Vacuum RTT floor	6.74 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	9.89 ms
Low-latency fiber material floor	9.85 ms
Engineering floor (5% path allowance)	10.39 ms
Research 1.33× mapped-fiber reference	13.15 ms
Estimated unamplified path loss	212.1 dB
Transparent optical spans / inline amplifiers	14 / 13

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.
