Moscow to Marseille RTT measurement: ICMP echo latency, jitter, packet loss, and route efficiency between Russia and France in round 2026-08-15T04:03:13Z.

🇷🇺 Moscow, Russia (MOW) → 🇫🇷 Marseille, France (MRS)

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

Measurement round 2026-08-15T04:03:13Z for Moscow-to-Marseille returned a 50.7 ms average ICMP echo RTT, with samples from 49.39 ms to 55.36 ms. The 1.41 ms standard deviation and 1.23 ms jitter kept the route in the Excellent latency tier, and all 50 probes were answered with zero packet loss.

Compared with the 26.23 ms straight-line fiber floor, the observed average is 1.93 times higher, putting direct-fiber efficiency at 51.7%. For this round the route ranked 6th among the 19 outbound paths, while the set's median variability, measured as standard deviation relative to average RTT, was 3.08%.

The combination of a tight sub-1.5 ms spread and no loss suggests the Moscow-to-Marseille path is well-behaved for a long European crossing, making this round a useful stability reference for ongoing RTT checks.

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: MOW → MRS

50 ICMP echo samples at 100 ms intervals · round 2026-08-15T04:03:13Z · avg 50.7 ± 0.20 ms (SE)

Sample distribution: box = interquartile range (49.8–51.0 ms), median 50.2 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 (26.2 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Moscow (55.75204, 37.61781) and Marseille (43.29695, 5.38107). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	2,678.2 km
Vacuum RTT floor	17.87 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	26.23 ms
Low-latency fiber material floor	26.12 ms
Engineering floor (5% path allowance)	27.54 ms
Research 1.33× mapped-fiber reference	34.88 ms
Estimated unamplified path loss	562.4 dB
Transparent optical spans / inline amplifiers	36 / 35
Published RTT inflation over fiber floor	1.93×

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.
