# Marseille, France → Moscow, Russia RTT

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

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

In round 2026-08-16T04:07:28Z, 50 ICMP probes from Marseille to Moscow returned an average round-trip time of 49.6 ms, with a minimum of 47.26 ms and a maximum of 58 ms. The 2.18 ms standard deviation and 1.92 ms jitter reflect a no-loss path whose variability keeps it in the excellent latency tier.

Among the 19 outbound routes measured from Marseille, this route ranks sixth by average latency. Its variability-to-average ratio sits above the 3.28% median across that route set, which is consistent with the much longer distance and the wider delay range captured in the sample.

The physical reference puts the Marseille-Moscow average at 1.89 times the theoretical fiber-floor latency, with a fiber-efficiency value of 52.9%. Moscow extends the backbone eastward toward European and Asia-Pacific networks, so this latency profile is particularly relevant for traffic moving between southern Europe and those farther regions. ICMP RTT is best read as a path-level indicator, not a proxy for end-user application performance.

## 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](/opendata/latency/). Per-pair files are available at `/opendata/latency/latest/pairs/mrs-mow.pings.{csv,json,yaml}`. When citing, include the route, the measurement round timestamp, and the dataset version — for example: "Hats Network latency dataset, Marseille → Moscow round 2026-08-16T04:07:28Z, CC BY 4.0".
