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

🇹🇼 Taipei, Taiwan (TPE) → 🇦🇺 Melbourne, Australia (MEL)

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

Measurement round 2026-08-16T04:07:28Z recorded 50 ICMP replies from Taipei to Melbourne with 0% packet loss. The average RTT was 142 ms, the minimum 135.86 ms, and the maximum 164.91 ms, giving a 6.17 ms standard deviation and 5.1 ms jitter.

On the 7,377.8 km great-circle distance, the average sits about 1.97 times the theoretical fiber floor of 72.25 ms, corresponding to 50.9% fiber efficiency. This places the route eighth among the 19 outbound paths measured from the same source in this round.

The network-wide median variability for the 19-route set is 3.28% of average latency; Melbourne's standard deviation is 4.3% of its average, so the path is more variable than the set's median route. The main route-specific insight is that lossless doesn't mean perfectly steady: latency moved across a 29 ms range even though no probes were lost.

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 → MEL

50 ICMP echo samples at 100 ms intervals · round 2026-08-16T04:07:28Z · avg 142.0 ± 0.87 ms (SE)

Sample distribution: box = interquartile range (138.1–144.7 ms), median 140.0 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 (72.3 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Taipei (25.05306, 121.52639) and Melbourne (-37.81400, 144.96332). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	7,377.8 km
Vacuum RTT floor	49.22 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	72.25 ms
Low-latency fiber material floor	71.96 ms
Engineering floor (5% path allowance)	75.87 ms
Research 1.33× mapped-fiber reference	96.09 ms
Estimated unamplified path loss	1549.3 dB
Transparent optical spans / inline amplifiers	97 / 96
Published RTT inflation over fiber floor	1.97×

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-mel.pings.{csv,json,yaml}.
