Live ICMP RTT measurements between Hong Kong, Hong Kong and Taipei, Taiwan, covering latency, jitter, packet loss and route efficiency.

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

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

ICMP echo RTT from Hong Kong to Taipei averaged 14.7 ms across 50 samples, with a minimum of 13.95 ms and a maximum of 17.24 ms. There was no packet loss and jitter was 0.56 ms, placing the route in the ultra-low latency tier.

The great-circle distance is 810.3 km, giving a vacuum floor of 5.41 ms and a fiber floor of 7.94 ms. Observed latency is 1.85 times the fiber floor, or 54 percent fiber efficiency, with an absolute overhead of roughly 6.8 ms over the direct-fiber reference.

This route ranks first among the 19 outbound paths from Hong Kong in measurement round 2026-08-16T04:07:28Z. Its standard deviation of 0.72 ms is only about 4.9 percent of the average, above the group's median standard deviation share of 3.28 percent, though the absolute jitter remains very small.

In practical terms, the route delivers the lowest RTT in the measured set while maintaining zero packet loss, making it a clear reference for low-latency connectivity from Hong Kong.

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 → TPE

50 ICMP echo samples at 100 ms intervals · round 2026-08-16T04:07:28Z · avg 14.7 ± 0.10 ms (SE)

Sample distribution: box = interquartile range (14.2–14.9 ms), median 14.5 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 Hong Kong (22.27832, 114.17469) and Taipei (25.05306, 121.52639). 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	1.85×

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