# Melbourne, Australia → New York, USA RTT

🇦🇺 **Melbourne, Australia (MEL)** → 🇺🇸 **New York, USA (NYC)**

Measurement round: `2026-08-16T04:07:28Z`.

The 2026-08-16T04:07:28Z round measured ICMP echo RTT between Melbourne, Australia and New York, USA across 50 samples. The average was 204.2 ms, with a minimum of 191.39 ms and a maximum of 227.39 ms; standard deviation was 8.13 ms, jitter was 7.67 ms, and packet loss was 0 percent.

At a geodesic distance of 16,672 km, the vacuum floor is 111.22 ms and the fiber floor is 163.27 ms. The observed average sits 1.25 times the fiber floor, equal to an 80 percent fiber efficiency; the extra delay over the physical reference is modest in absolute terms.

This route ranks 10th among 19 outbound routes in the same round, placing it in the middle of the set. Its standard deviation is about 4.0 percent of the average RTT, close to the median variability of 3.28 percent across the route set. With no packet loss and jitter under 8 ms, the main constraint is the absolute RTT rather than consistency.

## 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](/opendata/latency/). Per-pair files are available at `/opendata/latency/latest/pairs/mel-nyc.pings.{csv,json,yaml}`. When citing, include the route, the measurement round timestamp, and the dataset version — for example: "Hats Network latency dataset, Melbourne → New York round 2026-08-16T04:07:28Z, CC BY 4.0".
