ICMP RTT measurement page for Taipei, Taiwan to Melbourne, Australia: 50 samples, average 143.6 ms round-trip, 0% loss, jitter 4.26 ms.

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

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

In measurement round 2026-08-15T04:03:13Z, 50 ICMP echo samples from Taipei, Taiwan to Melbourne, Australia produced an average round-trip time of 143.6 ms, with a minimum of 137.35 ms and a maximum of 161.06 ms. The standard deviation was 4.85 ms, jitter was 4.26 ms, and packet loss was 0% for the sample window.

The route ranks eighth among the 19 outbound routes in this measurement set. Its standard-deviation-to-average ratio is about 3.38%, slightly above the 3.08% median for that outbound set, so the cross-sample spread is a bit wider than the midpoint route while still showing no lost packets.

For the 7,377.8 km geodesic distance, the fiber-floor estimate is 72.25 ms, and the observed 143.6 ms average is 1.99 times that floor, or about 50.3% fiber-path efficiency. The 'Good' latency tier fits a route where roughly half of the measured RTT is tied to direct distance and the rest is path overhead captured in this round.

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 2026-08-15T04:03:13Z · avg 143.6 ± 0.69 ms (SE)

Sample distribution: box = interquartile range (139.9–145.3 ms), median 142.8 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	1.99×

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}.
