ICMP round-trip latency from Melbourne, Australia to Marseille, France: average RTT, jitter, loss, and distance-adjusted route data.

🇦🇺 Melbourne, Australia (MEL) → 🇫🇷 Marseille, France (MRS)

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

In the 2026-08-16T04:07:28Z measurement round, ICMP echo requests from Melbourne, Australia to Marseille, France returned an average round-trip time of 233.5 ms over 50 probes, with a low of 221.74 ms and a high of 271.93 ms. The route lost no packets and earned a Fair latency classification.

Against a straight-line fiber path, this average is 1.44 times the theoretical fiber floor of roughly 162 ms, placing the route at 69.5 percent fiber efficiency over a geodesic distance of 16,579.2 km. That gap is a useful distance-adjusted sign of how intercontinental transport overhead accumulates.

This route ranked 11th among the 19 route pairs measured in the same round. Its standard deviation of 10.3 ms is about 4.4 percent of the average RTT, somewhat above the route-set median of 3.28 percent, while jitter averaged 8.57 ms.

Given Marseille's role as a Mediterranean cable landing hub, this measurement offers a useful Melbourne-to-southern-Europe reference point for steady, loss-free ICMP reachability.

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: MEL → MRS

50 ICMP echo samples at 100 ms intervals · round 2026-08-16T04:07:28Z · avg 233.5 ± 1.46 ms (SE)

Sample distribution: box = interquartile range (225.6–238.3 ms), median 229.9 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 (162.4 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Melbourne (-37.81400, 144.96332) and Marseille (43.29695, 5.38107). It does not disclose either facility address.

Vacuum RTT floor	110.6 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	162.36 ms
Low-latency fiber material floor	161.7 ms
Engineering floor (5% path allowance)	170.5 ms
Research 1.33× mapped-fiber reference	215.93 ms
Estimated unamplified path loss	3481.6 dB
Transparent optical spans / inline amplifiers	218 / 217
Published RTT inflation over fiber floor	1.44×

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.
