ICMP RTT measurements from Amsterdam, Netherlands to Hong Kong: average 155.9 ms, jitter, packet loss, and route efficiency for this fair-latency path.

🇳🇱 Amsterdam, Netherlands (AMS) → 🇭🇰 Hong Kong (HKG)

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

For the 2026-08-16T04:07:28Z measurement round, ICMP echo RTT from Amsterdam to Hong Kong averaged 155.9 ms, with a minimum of 149.39 ms and a maximum of 177.73 ms. All 50 probes were answered, so the zero packet loss and 4.48 ms jitter describe a stable sample rather than a lossy path.

The great-circle distance of 9,297.6 km gives a vacuum light-time floor of 62.03 ms and a realistic fiber floor of 91.05 ms. The observed average is 1.71 times that fiber floor, which translates to a fiber efficiency of 58.4%; the extra time over the floor is the route's real-world distance penalty.

This route ranks 12th among the 19 outbound routes measured from Amsterdam in this round. Its standard deviation of 5.82 ms is about 3.7% of the average, slightly above the 3.28% median variability for the 19-route set, so the path is consistent but a touch more variable than the midpoint of the group.

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: AMS → HKG

50 ICMP echo samples at 100 ms intervals · round 2026-08-16T04:07:28Z · avg 155.9 ± 0.82 ms (SE)

Sample distribution: box = interquartile range (151.9–157.5 ms), median 155.2 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 (91.0 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Amsterdam (52.37403, 4.88969) and Hong Kong (22.27832, 114.17469). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	9,297.6 km
Vacuum RTT floor	62.03 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	91.05 ms
Low-latency fiber material floor	90.68 ms
Engineering floor (5% path allowance)	95.61 ms
Research 1.33× mapped-fiber reference	121.1 ms
Estimated unamplified path loss	1952.5 dB
Transparent optical spans / inline amplifiers	123 / 122
Published RTT inflation over fiber floor	1.71×

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.
