Hong Kong, Hong Kong to Marseille, France ICMP RTT measurement: 165.4 ms average, 159.87 ms min, 180.73 ms max, 0% loss over 50 samples.

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

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

In the 2026-08-16T04:07:28Z round, 50 ICMP echo probes sent 100 ms apart from Hong Kong to Marseille recorded zero packet loss, with an average round-trip time of 165.4 ms, a minimum of 159.87 ms, and a maximum of 180.73 ms. The standard deviation was 4.35 ms and jitter was 3.54 ms, so the sample was relatively contained.

The 9,750.5 km great-circle distance gives a round-trip vacuum floor of 65.05 ms and a fiber floor of 95.48 ms. At 165.4 ms, the average is 1.73 times the fiber floor, or 57.7 percent fiber efficiency, with an excess of 69.92 ms over the straight-line fiber minimum.

This route ranked 14th of the 19 outbound paths measured from Hong Kong in the same round. Its standard-deviation-to-average ratio was about 2.63 percent, below the 3.28 percent median for the group, so the round-trip times were more consistent than the typical path in the same measurement set.

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: HKG → MRS

50 ICMP echo samples at 100 ms intervals · round 2026-08-16T04:07:28Z · avg 165.4 ± 0.62 ms (SE)

Sample distribution: box = interquartile range (162.0–167.6 ms), median 164.6 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 Hong Kong (22.27832, 114.17469) and Marseille (43.29695, 5.38107). 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	1.73×

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.
