# Marseille, France → New York, USA RTT

🇫🇷 **Marseille, France (MRS)** → 🇺🇸 **New York, USA (NYC)**

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

In the 2026-08-16T04:07:28Z round, ICMP echo RTT from Marseille, France, to New York, USA, averaged 79.8 ms across 50 samples, ranging from 75.53 ms to 89.73 ms. The route logged zero packet loss and earned an Excellent latency rating.

The 6,321.9 km great-circle distance yields a theoretical fiber-floor RTT of 61.91 ms, so the observed mean sits just 1.29 times above that floor at 77.6% fiber efficiency. With a standard deviation of 3.65 ms and jitter of 3.14 ms, the path was both fast and consistent.

This route ranked 7th among 19 outbound routes from Marseille in the same round, against a network-wide median standard-deviation-to-average ratio of 3.28%. The result gives operators a strong low-latency benchmark for Southern Europe-to-US East Coast connectivity.

## 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-nyc.pings.{csv,json,yaml}`. When citing, include the route, the measurement round timestamp, and the dataset version — for example: "Hats Network latency dataset, Marseille → New York round 2026-08-16T04:07:28Z, CC BY 4.0".
