Frankfurt, Germany to Hong Kong, Hong Kong ICMP RTT measurement: 151.2 ms average, 146.58–165.36 ms range, zero packet loss over 50 samples.

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

Measurement round: 2026-08-15T04:03:13Z.

Round 2026-08-15T04:03:13Z measured Frankfurt, Germany to Hong Kong at 151.2 ms average ICMP RTT, with a 146.58 ms minimum and 165.36 ms maximum across 50 samples and zero packet loss.

The 9,177.1 km great-circle distance gives a 61.22 ms vacuum round-trip floor and an 89.87 ms fiber round-trip floor; the measured 151.2 ms is 1.68 times the fiber floor, translating to about 59% fiber efficiency for this Asia-Pacific path.

This route ranked 12th among the 19 outbound routes in the same round. Its 4.14 ms standard deviation equals roughly 2.7% of the average, below the round's median spread of 3.08%, and jitter of 3.56 ms with no loss makes the Fair tier both usable and steady.

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: FRA → HKG

50 ICMP echo samples at 100 ms intervals · round 2026-08-15T04:03:13Z · avg 151.2 ± 0.59 ms (SE)

Sample distribution: box = interquartile range (148.1–153.4 ms), median 149.9 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 Frankfurt am Main (50.11552, 8.68417) and Hong Kong (22.27832, 114.17469). 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.

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