Explore Sydney, Australia to Taipei, Taiwan ICMP RTT, jitter, packet loss and fiber latency limits on the AS203314 network.

🇦🇺 Sydney, Australia (SYD) → 🇹🇼 Taipei, Taiwan (TPE)

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

Sydney to Taipei averaged 131.7 ms across 50 replies. The observed range was 126.36 to 151.94 ms; these figures describe one probe round, not a long-term service target.

This is number 4 of 19 outgoing routes by average RTT. That ranking compares different destinations and is not adjusted for distance.

Ping Measurement Series

50 ICMP echo probes were recorded in this round. Individual replies and their distribution are shown below.

Ping series: SYD → TPE

50 ICMP echo samples at 100 ms intervals · round 2026-08-16T04:07:28Z · avg 131.7 ± 0.63 ms (SE)

Sample distribution: box = interquartile range (128.4–133.6 ms), median 131.0 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 (70.9 ms) for this route.

Theoretical Fiber Latency

The propagation model uses public city-centre coordinates from GeoNames: Sydney (-33.86785, 151.20732) and Taipei (25.05306, 121.52639). These are not facility coordinates or a surveyed cable path.

Physical Reference	Value
WGS-84 geodesic distance	7,237.6 km
Vacuum RTT floor	48.28 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	70.88 ms
Low-latency fiber material floor	70.59 ms
Engineering floor (5% path allowance)	74.43 ms
Research 1.33× mapped-fiber reference	94.26 ms
Estimated unamplified path loss	1519.9 dB
Transparent optical spans / inline amplifiers	95 / 94
Published RTT inflation over fiber floor	1.86×

The span count assumes 80 km optical spans. Attenuation is a power-loss term, not a propagation delay. See the model assumptions and equations.

About This Measurement

These ICMP measurements cover the two backbone endpoints. Access networks, routing policy and load can change an end user's result. A probe round is not an SLA.
