ICMP RTT measurements from New York, USA to Sydney, Australia: average latency, jitter, packet loss, and route efficiency for this 15,988 km pair.

🇺🇸 New York, USA (NYC) → 🇦🇺 Sydney, Australia (SYD)

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

In the 2026-08-15T04:03:13Z round, ICMP echo RTT from New York, USA to Sydney, Australia averaged 193.6 ms, with minimum 188.9 ms and maximum 208.74 ms over 50 samples. Jitter was 2.94 ms and packet loss was 0 percent, so every probe was answered.

The 193.6 ms average is 24 percent above the 156.57 ms fiber-floor estimate for the 15,988.1 km great-circle distance, equivalent to 80.9 percent fiber-floor efficiency. This pair ranked 16th among the 19 routes leaving the same origin in the round, and its standard-deviation-to-average ratio of about 2.1 percent is clearly below the 3.08 percent median across those routes.

The notable takeaway is consistency: a standard deviation of only 4.14 ms and a narrow max-min spread of 19.84 ms make this one of the steadier long-haul profiles in the route set, even though its absolute RTT is not at the top of the ranking. The fiber efficiency is also strong, indicating the path is delivering close to its theoretical latency limit.

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: NYC → SYD

50 ICMP echo samples at 100 ms intervals · round 2026-08-15T04:03:13Z · avg 193.6 ± 0.59 ms (SE)

Sample distribution: box = interquartile range (190.5–195.5 ms), median 192.6 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 (156.6 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for New York City (40.71427, -74.00597) and Sydney (-33.86785, 151.20732). It does not disclose either facility address.

Vacuum RTT floor	106.66 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	156.57 ms
Low-latency fiber material floor	155.94 ms
Engineering floor (5% path allowance)	164.42 ms

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