Hong Kong to Taipei, Taiwan ICMP RTT: 15.2 ms average latency, zero packet loss, and ultra-low jitter from the 2026-08-15 round.

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

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

In the 2026-08-15T04:03:13Z round, ICMP echo RTT from Hong Kong to Taipei averaged 15.2 ms, with a minimum of 14.92 ms and a maximum of 16.06 ms over 50 samples. There was no packet loss, and jitter was just 0.21 ms, positioning this route as the top-ranked outbound path among the 19 routes measured in this round.

The observed average is 1.92 times the 7.94 ms fiber floor for the 810 km distance, corresponding to 52.2% fiber efficiency. Despite the low absolute latency, the route still carries a modest overhead relative to the optical floor; that gap is consistent with the cable path being longer than the straight-line distance and with per-hop network forwarding.

With a standard deviation of 0.25 ms, the variability ratio is about 1.6%, well below the 3.08% median for the route set. This makes the Hong Kong-Taipei corridor an exceptionally consistent baseline, and the tight min-max range reinforces that impression.

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 2026-08-15T04:03:13Z · avg 15.2 ± 0.04 ms (SE)

Sample distribution: box = interquartile range (15.0–15.3 ms), median 15.1 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

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

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.

Per-pair files are available at /opendata/latency/latest/pairs/hkg-tpe.pings.{csv,json,yaml}.
