Marseille, France to Hong Kong, Hong Kong ICMP RTT measurements: average, minimum, maximum, jitter, packet loss, standard deviation, and route efficiency.

🇫🇷 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.

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: MRS → HKG

50 ICMP echo samples at 100 ms intervals · round 2026-08-16T04:07:28Z · avg 166.4 ± 0.49 ms (SE)

Sample distribution: box = interquartile range (163.7–167.8 ms), median 166.3 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 (95.5 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Marseille (43.29695, 5.38107) and Hong Kong (22.27832, 114.17469). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	9,750.5 km
Vacuum RTT floor	65.05 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	95.48 ms
Low-latency fiber material floor	95.1 ms
Engineering floor (5% path allowance)	100.27 ms
Research 1.33× mapped-fiber reference	126.99 ms
Estimated unamplified path loss	2047.6 dB
Transparent optical spans / inline amplifiers	128 / 127
Published RTT inflation over fiber floor	1.74×

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