Sydney, Australia to Moscow, Russia ICMP RTT measurement: average, minimum, maximum, jitter, packet loss, and route efficiency for this long-haul path.

🇦🇺 Sydney, Australia (SYD) → 🇷🇺 Moscow, Russia (MOW)

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

In the 2026-08-15T04:03:13Z round, ICMP echo probes from Sydney, Australia to Moscow, Russia recorded an average round-trip time of 242.3 ms, with a minimum of 230.31 ms and a maximum of 283.82 ms across 50 samples. Zero packet loss was observed, but the 11.25 ms standard deviation and 7.19 ms jitter indicate some short-term variability on this long-haul path.

The measured average is 1.71 times the theoretical fiber-floor minimum for the great-circle distance, translating to a fiber efficiency of 58.5%. That gap suggests a noticeably indirect optical route, even though the achieved latency is still placed in the fair tier.

This path ranked 12th among the 19 outbound routes in the round. Its relative spread of about 4.6% of the average is wider than the 3.1% median relative spread seen across the route set, so the connection is stable in loss terms but more variable in timing than a typical peer path.

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 → MOW

50 ICMP echo samples at 100 ms intervals · round 2026-08-15T04:03:13Z · avg 242.3 ± 1.59 ms (SE)

Sample distribution: box = interquartile range (234.6–245.7 ms), median 239.2 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 (141.8 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Sydney (-33.86785, 151.20732) and Moscow (55.75204, 37.61781). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	14,483.9 km
Vacuum RTT floor	96.63 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	141.84 ms
Low-latency fiber material floor	141.27 ms
Engineering floor (5% path allowance)	148.95 ms
Research 1.33× mapped-fiber reference	188.64 ms
Estimated unamplified path loss	3041.6 dB
Transparent optical spans / inline amplifiers	191 / 190
Published RTT inflation over fiber floor	1.71×

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.
