Moscow, Russia to Marseille, France: ICMP RTT measurement with 49.9 ms average, zero loss, and excellent stability over 50 samples.

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

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

For the 2026-08-16T04:07:28Z round, ICMP echo RTT from Moscow to Marseille averaged 49.9 ms over 50 samples, with a 47.94 ms minimum and 53.35 ms maximum; jitter was 1.46 ms and packet loss was zero, placing the pair in the excellent latency tier.

The average is about 1.9 times the 26.23 ms theoretical fiber floor for the 2,678.2 km geodesic separation, a 52.6% efficiency ratio. Among the 19 Moscow-origin routes in this round, this path ranks sixth by average RTT, and its spread-to-average ratio of roughly 2.9% is below the 3.28% median for the route set.

The sample was uniformly clean: the maximum ran only 3.45 ms above the average, and no packets were lost. For the Mediterranean landing direction, the route offers a tightly bounded latency profile rather than a low-floor-only result.

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 2026-08-16T04:07:28Z · avg 49.9 ± 0.21 ms (SE)

Sample distribution: box = interquartile range (48.7–51.1 ms), median 49.4 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	1.9×

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