Moscow, Russia → Marseille, France RTT

Explore Moscow, Russia to Marseille, France ICMP RTT, jitter, packet loss and fiber latency limits on the AS203314 network.

Open Data

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

Measurement round: 2026-10-20T08:46:17Z.

Moscow to Marseille averaged 51.5 ms and ranked sixth of 19 outbound routes. Results ranged from 48.33 to 58.16 ms, with no measured loss.

The average is about twice the fiber reference. Its wider spread than Moscow's nearer European routes makes the mean a less complete description of this sample.

Ping Measurement Series

50 ICMP echo probes were recorded in this round. Individual replies and their distribution are shown below.

Ping series: MOW → MRS

50 ICMP echo samples at 100 ms intervals · round 2026-10-20T08:46:17Z · avg 51.5 ± 0.36 ms (SE)

Sample distribution: box = interquartile range (49.6–52.3 ms), median 50.5 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 propagation model uses public city-centre coordinates from GeoNames: Moscow (55.75204, 37.61781) and Marseille (43.29695, 5.38107). These are not facility coordinates or a surveyed cable path.

The span count assumes 80 km optical spans. Attenuation is a power-loss term, not a propagation delay. See the model assumptions and equations.

About This Measurement

These ICMP measurements cover the two backbone endpoints. Access networks, routing policy and load can change an end user's result. A probe round is not an SLA.

The underlying replies are available 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}.
