# Marseille, France → Hong Kong RTT

🇫🇷 **Marseille, France (MRS)** → 🇭🇰 **Hong Kong (HKG)**

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

For the 2026-08-16T04:07:28Z round, Marseille, France to Hong Kong produced an average ICMP round-trip time of 166.4 ms, with a minimum of 161.4 ms and maximum of 176.84 ms. All 50 probes returned, with no packet loss; jitter was 2.92 ms and standard deviation was 3.5 ms.

This Fair-tier result is 1.74 times the theoretical fiber floor of 95.48 ms, corresponding to a route efficiency of 57.4%. The path ranks 13th among the 19 outbound routes in this round, and its variability relative to the average is about 2.1%, comfortably below the 3.28% median across the 19 outbound paths.

The useful signal from this round is consistency: across more than 9,700 km, the low jitter and zero loss make the RTT highly predictable. The average is still far from the shortest possible fiber time, but the route behaves steadily for an intercontinental path.

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