Singapore to Marseille France ICMP RTT page: average latency, packet loss, jitter, and distance efficiency from 50 samples in round 2026-08-16T04:07:28Z.

🇸🇬 Singapore (SIN) → 🇫🇷 Marseille, France (MRS)

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

Under the 2026-08-16T04:07:28Z measurement round, ICMP echo probes from Singapore to Marseille, France, delivered an average round-trip time of 140.6 ms, with a minimum of 138.21 ms, a maximum of 150.15 ms, and zero packet loss over 50 samples. The spread between fastest and slowest probes was just under 12 ms, with a standard deviation of 2.29 ms and jitter of 1.84 ms.

On a straight-line distance of 10,598.5 km, the direct fiber floor is about 103.79 ms. The observed 140.6 ms average is 1.35 times that floor, translating to a fiber efficiency of 73.8%, a tight result for a route spanning more than 10,000 km.

This route ranked 6th among the 19 outbound routes measured from Singapore in the same round. Its low standard deviation is well under the network-wide median ratio of 3.28% of average RTT, so the path is both competitive and consistently stable for ICMP echo traffic.

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: SIN → MRS

50 ICMP echo samples at 100 ms intervals · round 2026-08-16T04:07:28Z · avg 140.6 ± 0.32 ms (SE)

Sample distribution: box = interquartile range (139.2–140.8 ms), median 140.0 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 (103.8 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Singapore (1.28967, 103.85007) and Marseille (43.29695, 5.38107). It does not disclose either facility address.

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.
