Measured ICMP RTT from Melbourne, Australia to Frankfurt, Germany: average latency, jitter, packet loss, and fiber-floor efficiency.

🇦🇺 Melbourne, Australia (MEL) → 🇩🇪 Frankfurt, Germany (FRA)

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

In the 2026-08-15T04:03:13Z measurement round, ICMP echo RTT from Melbourne to Frankfurt averaged 250.5 ms over 50 samples, with a minimum of 242.88 ms and a maximum of 267.73 ms. No packets were lost, and jitter was 5.71 ms.

The geodesic distance of 16,315.5 km corresponds to a vacuum floor of 108.85 ms and an all-fiber floor of 159.77 ms. The measured average is 1.57 times the fiber floor, or 63.8% fiber efficiency, so the route is performing reasonably close to the physical limits for the distance.

This path ranked 14th out of 19 outbound routes by average latency from this source. The standard deviation of 5.99 ms is 2.39% of the average, well below the 3.08% network-wide median for standard deviation as a share of average.

The zero loss and 5.71 ms jitter indicate a consistent measurement window, while the 1.57x inflation over the fiber floor gives future measurements a concrete reference for this route.

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: MEL → FRA

50 ICMP echo samples at 100 ms intervals · round 2026-08-15T04:03:13Z · avg 250.5 ± 0.85 ms (SE)

Sample distribution: box = interquartile range (245.9–253.9 ms), median 249.0 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 (159.8 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Melbourne (-37.81400, 144.96332) and Frankfurt am Main (50.11552, 8.68417). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	16,315.5 km
Vacuum RTT floor	108.85 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	159.77 ms
Low-latency fiber material floor	159.13 ms
Engineering floor (5% path allowance)	167.78 ms
Research 1.33× mapped-fiber reference	212.5 ms
Estimated unamplified path loss	3426.2 dB
Transparent optical spans / inline amplifiers	215 / 214
Published RTT inflation over fiber floor	1.57×

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.
