Live ICMP RTT measurements between Hong Kong, Hong Kong and Paris, France: 50-probe averages, jitter, packet loss, and route efficiency.

🇭🇰 Hong Kong (HKG) → 🇫🇷 Paris, France (PAR)

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

In the 2026-08-16T04:07:28Z measurement round, 50 ICMP echo probes from Hong Kong to Paris were sent at 100 ms intervals, and none were lost. The average round-trip time was 159.4 ms, with observed values between a minimum of 154.31 ms and a maximum of 174.31 ms.

The route's 4.8 ms standard deviation and 4.33 ms jitter place it in the Fair latency tier. It ranks thirteenth among the 19 outbound routes from Hong Kong measured in this round, and its variation coefficient of roughly 3.0 percent sits close to the 3.28 percent median for that group.

Geometrically, the 9,647.6 km great-circle route has a fiber-floor RTT of 94.48 ms, so the observed average is 1.69 times the floor and fiber efficiency is 59.3 percent. Zero packet loss is a positive signal for reachability, while the spread around the average suggests a typical long-haul profile in this Hong Kong outbound 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 → PAR

50 ICMP echo samples at 100 ms intervals · round 2026-08-16T04:07:28Z · avg 159.4 ± 0.68 ms (SE)

Sample distribution: box = interquartile range (155.9–161.2 ms), median 158.0 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 (94.5 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Hong Kong (22.27832, 114.17469) and Paris (48.85341, 2.34880). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	9,647.6 km
Vacuum RTT floor	64.36 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	94.48 ms
Low-latency fiber material floor	94.1 ms
Engineering floor (5% path allowance)	99.21 ms
Research 1.33× mapped-fiber reference	125.65 ms
Estimated unamplified path loss	2026 dB
Transparent optical spans / inline amplifiers	127 / 126
Published RTT inflation over fiber floor	1.69×

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.
