Hong Kong, Hong Kong to Frankfurt, Germany ICMP RTT measurement: 150.7 ms average, 147.02 ms min, 163.83 ms max, 0% loss over 50 samples.

🇭🇰 Hong Kong (HKG) → 🇩🇪 Frankfurt, Germany (FRA)

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 Frankfurt returned with zero packet loss, giving an average round-trip time of 150.7 ms, a minimum of 147.02 ms, and a maximum of 163.83 ms. The standard deviation was 3.53 ms and jitter was 2.66 ms, so the path stayed fairly steady across the sample.

The 9,177.1 km great-circle distance sets a round-trip vacuum floor of 61.22 ms and a fiber floor of 89.87 ms. The 150.7 ms average is 1.68 times that fiber floor, which corresponds to 59.6 percent fiber efficiency and a 60.83 ms difference from the straight-line fiber minimum.

Within the same round, this route ranked 10th among 19 outbound paths measured from Hong Kong. The median standard-deviation-to-average ratio for those paths was 3.28 percent; this route's ratio was about 2.34 percent, indicating latency variation below the typical level for the 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 → FRA

50 ICMP echo samples at 100 ms intervals · round 2026-08-16T04:07:28Z · avg 150.7 ± 0.50 ms (SE)

Sample distribution: box = interquartile range (148.7–151.2 ms), median 149.8 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 (89.9 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Hong Kong (22.27832, 114.17469) and Frankfurt am Main (50.11552, 8.68417). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	9,177.1 km
Vacuum RTT floor	61.22 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	89.87 ms
Low-latency fiber material floor	89.51 ms
Engineering floor (5% path allowance)	94.37 ms
Research 1.33× mapped-fiber reference	119.53 ms
Estimated unamplified path loss	1927.2 dB
Transparent optical spans / inline amplifiers	121 / 120
Published RTT inflation over fiber floor	1.68×

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.
