ICMP echo RTT from Singapore to Marseille, France: 138.8 ms average, 0% loss, 50 samples from the 2026-08-15T04:03:13Z round.

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

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

For the 2026-08-15T04:03:13Z round, ICMP echo RTT between Singapore and Marseille averaged 138.8 ms over 50 samples, with a minimum of 134.54 ms and a maximum of 146.66 ms. The 3.05 ms standard deviation and 2.93 ms jitter indicate a consistently paced path, and every probe came back without loss.

Compared with the straight-line fiber-floor reference for the 10,598.5 km separation, the measured average is 1.34 times higher, giving a fiber efficiency of 74.8%. That is a relatively efficient result for a long intercontinental route and suggests the path is not far from the physical lower bound.

This route was ranked 6th among the 19 outbound routes measured from Singapore in the same round. With the group's median standard-deviation-to-average ratio at 3.08%, this route's stability is near the typical range while its average latency is among the better performers.

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 2026-08-15T04:03:13Z · avg 138.8 ± 0.43 ms (SE)

Sample distribution: box = interquartile range (136.6–140.3 ms), median 138.1 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 (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.

Physical Reference	Value
WGS-84 geodesic distance	10,598.5 km
Vacuum RTT floor	70.71 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	103.79 ms
Low-latency fiber material floor	103.37 ms
Engineering floor (5% path allowance)	108.99 ms
Research 1.33× mapped-fiber reference	138.04 ms
Estimated unamplified path loss	2225.7 dB
Transparent optical spans / inline amplifiers	140 / 139
Published RTT inflation over fiber floor	1.34×

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.

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/sin-mrs.pings.{csv,json,yaml}.
