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

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

Round 2026-08-15T04:03:13Z measured ICMP echo RTT from Sydney to Berlin at an average of 262.1 ms, with samples ranging from 254.82 ms to 282.79 ms. All 50 probes succeeded, so packet loss was 0% on this high-latency route.

The great-circle distance is 16,087.7 km, placing the theoretical fiber RTT floor near 157.54 ms. The observed average is 1.66 times that floor, or 60.1% fiber efficiency, leaving relatively little overhead for an intercontinental path.

This pair is listed 17th among the 19 routes in the round. Its variability is contained, with a standard deviation of 5.56 ms and jitter of 4.58 ms, both well below the network-wide median variability of 3.08% relative to the average. The stable distribution means the practical concern is the ~260 ms baseline rather than sudden swings in round-trip time.

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: SYD → BER

50 ICMP echo samples at 100 ms intervals · round 2026-08-15T04:03:13Z · avg 262.1 ± 0.79 ms (SE)

Sample distribution: box = interquartile range (259.1–264.0 ms), median 261.0 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 (157.5 ms) for this route.

Theoretical Fiber Latency

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

Physical Reference	Value
WGS-84 geodesic distance	16,087.7 km
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
Estimated unamplified path loss	3378.4 dB
Transparent optical spans / inline amplifiers	212 / 211
Published RTT inflation over fiber floor	1.66×

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/syd-ber.pings.{csv,json,yaml}.
