ICMP round-trip time measurements from Taipei, Taiwan to Hong Kong, Hong Kong: latency averages, jitter, packet loss and route performance.

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

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

Over 50 ICMP probes in measurement round 2026-08-16T04:07:28Z, the Taipei-to-Hong Kong path averaged 15.5 ms, with a minimum of 15.09 ms and a maximum of 17.58 ms. The 0.41 ms standard deviation and 0.34 ms jitter show a very tight latency envelope, and the 0% packet loss means every probe received a reply.

The route ranks first among the 19 outbound paths measured from Taipei in this round. That top position is supported by an average only 1.95 times the theoretical fiber floor for the 810 km great-circle distance; the measured fiber efficiency is 51.2%.

The network-wide median variability across the same 19-route outbound set is 3.28% relative to average latency. This route's standard deviation is about 2.6% of its average, so it is not only fast but also steadier than the typical route in the set. For a short Asia-Pacific path like this one, the main takeaway is consistent ultra-low latency with zero loss.

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 2026-08-16T04:07:28Z · avg 15.5 ± 0.06 ms (SE)

Sample distribution: box = interquartile range (15.2–15.7 ms), median 15.4 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	1.95×

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}.
