ICMP RTT measurement page for Taipei, Taiwan to Hong Kong, Hong Kong: 50 samples, average 15.4 ms round-trip, 0% loss, jitter 0.35 ms.

🇹🇼 Taipei, Taiwan (TPE) → 🇭🇰 Hong Kong (HKG)

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

In measurement round 2026-08-15T04:03:13Z, 50 ICMP echo samples from Taipei, Taiwan to Hong Kong, Hong Kong returned an average round-trip time of 15.4 ms, with a minimum of 14.93 ms and a maximum of 17.64 ms. The standard deviation of 0.45 ms and jitter of 0.35 ms show a stable sampling window, and packet loss was 0%.

Relative to the 19 outbound routes in this measurement set, the route is ranked first. Its standard-deviation-to-average ratio is about 2.92%, below the 3.08% median for that outbound set, so this route is not only fast but also comparatively consistent.

For the 810.3 km direct-line distance, the fiber-floor estimate is 7.94 ms; the measured average is 1.94 times that floor, equivalent to a fiber-path efficiency of about 51.5%. With the 'Ultra-Low' latency tier and zero packet loss, the Taipei-Hong Kong round is a tightly bounded, loss-free regional measurement.

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: TPE → HKG

50 ICMP echo samples at 100 ms intervals · round 2026-08-15T04:03:13Z · avg 15.4 ± 0.06 ms (SE)

Sample distribution: box = interquartile range (15.1–15.5 ms), median 15.3 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 (7.9 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Taipei (25.05306, 121.52639) and Hong Kong (22.27832, 114.17469). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	810.3 km
Vacuum RTT floor	5.41 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	7.94 ms
Low-latency fiber material floor	7.9 ms
Engineering floor (5% path allowance)	8.33 ms
Research 1.33× mapped-fiber reference	10.55 ms
Estimated unamplified path loss	170.2 dB
Transparent optical spans / inline amplifiers	11 / 10
Published RTT inflation over fiber floor	1.94×

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/tpe-hkg.pings.{csv,json,yaml}. When citing, include the route, the measurement round timestamp, and the dataset version — for example: "Hats Network latency dataset, Taipei → Hong Kong round 2026-08-15T04:03:13Z, CC BY 4.0".
