Frankfurt to Sydney, Germany to Australia ICMP round-trip time: 50-sample latency, packet loss, jitter and route efficiency metrics.

🇩🇪 Frankfurt, Germany (FRA) → 🇦🇺 Sydney, Australia (SYD)

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

During the 2026-08-15T04:03:13Z round, 50 ICMP echo requests from Frankfurt to Sydney averaged 256.5 ms, with a minimum of 240.87 ms and a maximum of 286.44 ms. No packets were lost, but the standard deviation reached 11.24 ms and jitter reached 12.01 ms.

Covering roughly 16,478 km, the route operates at 1.59 times the theoretical fiber floor of 161.37 ms, equivalent to about 62.9% fiber efficiency. The 256.5 ms average is typical for such a long physical path, with the higher jitter reflecting the larger spread between the fastest and slowest samples.

Among the 19 measured routes this path ranks 19th, and its 4.38% variation around the average exceeds the 3.08% median spread-to-average ratio for the set. For Frankfurt-to-Sydney route checks, the practical range is about 240-286 ms, with no loss and jitter near 12 ms.

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: FRA → SYD

50 ICMP echo samples at 100 ms intervals · round 2026-08-15T04:03:13Z · avg 256.5 ± 1.59 ms (SE)

Sample distribution: box = interquartile range (248.7–261.7 ms), median 253.6 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 (161.4 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Frankfurt am Main (50.11552, 8.68417) and Sydney (-33.86785, 151.20732). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	16,478.2 km
Vacuum RTT floor	109.93 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	161.37 ms
Low-latency fiber material floor	160.72 ms
Engineering floor (5% path allowance)	169.46 ms
Research 1.33× mapped-fiber reference	214.62 ms
Estimated unamplified path loss	3460.4 dB
Transparent optical spans / inline amplifiers	217 / 216
Published RTT inflation over fiber floor	1.59×

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.
