Berlin (Germany) to Sydney (Australia): 50-sample ICMP round-trip times, jitter, loss, and fiber-efficiency context for a 16,087 km route.

🇩🇪 Berlin, Germany (BER) → 🇦🇺 Sydney, Australia (SYD)

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

In measurement round 2026-08-15T04:03:13Z, the Berlin-Sydney route recorded an average ICMP round-trip time of 262.6 ms across 50 samples, with a minimum of 255.85 ms and a maximum of 280.63 ms. No packets were lost, and the 4.85 ms standard deviation with 5.22 ms jitter shows a consistent distribution for such a long haul.

At 16,087 km, the theoretical fiber floor is 157.54 ms; the observed average is 1.67 times that floor, or 60% fiber efficiency. The high latency tier is consistent with the distance, and the tight spread shows that the added time is not accompanied by erratic behavior.

This route ranked 19th out of 19 outbound routes in the round, while the typical route-level variability across the network was 3.08% of average latency. Its standard deviation is about 1.8% of its average RTT, lower than that typical variability, making the highest-latency route in the set a notably consistent one in relative terms.

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: BER → SYD

50 ICMP echo samples at 100 ms intervals · round 2026-08-15T04:03:13Z · avg 262.6 ± 0.69 ms (SE)

Sample distribution: box = interquartile range (259.2–264.9 ms), median 261.8 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 (157.5 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Berlin (52.52437, 13.41053) and Sydney (-33.86785, 151.20732). It does not disclose either facility address.

Vacuum RTT floor	107.33 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	157.54 ms
Low-latency fiber material floor	156.91 ms
Engineering floor (5% path allowance)	165.44 ms
Research 1.33× mapped-fiber reference	209.53 ms

Transparent optical spans / inline amplifiers	212 / 211
Published RTT inflation over fiber floor	1.67×

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.
