ICMP echo RTT data from the 2026-08-15 round for Moscow (Russia) to Sydney (Australia): average, min, max, jitter, packet loss.

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

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

During the 2026-08-15T04:03:13Z ICMP echo round, Moscow to Sydney recorded an average RTT of 243.6 ms over 50 samples at a 100 ms interval, with 233.31 ms as the minimum and 269.22 ms as the maximum. The standard deviation was 8.15 ms, jitter was 7.59 ms, and packet loss was 0%.

The great-circle distance is 14,483.9 km, which places the vacuum floor at 96.63 ms and the straight fiber floor at 141.84 ms. The measured average is 1.72x the fiber floor, or 58.2% fiber efficiency, and the latency tier is Fair.

Across the 19 Moscow outbound routes measured in this round, this path ranked 19th, and its RTT variability was about 3.3% of the average — slightly above the round's median variability ratio of 3.08%. The lossless sample and contained jitter indicate a stable ICMP reachability result over a very long distance.

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: MOW → SYD

50 ICMP echo samples at 100 ms intervals · round 2026-08-15T04:03:13Z · avg 243.6 ± 1.15 ms (SE)

Sample distribution: box = interquartile range (238.5–246.6 ms), median 241.5 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 Moscow (55.75204, 37.61781) and Sydney (-33.86785, 151.20732). 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	1.72×

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