# Hong Kong → Taipei, Taiwan RTT

🇭🇰 **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.

## 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](/opendata/latency/). Per-pair files are available at `/opendata/latency/latest/pairs/hkg-tpe.pings.{csv,json,yaml}`. When citing, include the route, the measurement round timestamp, and the dataset version — for example: "Hats Network latency dataset, Hong Kong → Taipei round 2026-08-16T04:07:28Z, CC BY 4.0".
