Live ICMP round-trip time from Melbourne, Australia to Miami, USA: average, min, max, jitter, packet loss, and latency stability context.

🇦🇺 Melbourne, Australia (MEL) → 🇺🇸 Miami, USA (MIA)

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

For the round from 2026-08-16T04:07:28Z, the 50 ICMP echo probes from Melbourne to Miami recorded an average RTT of 201 ms, with a minimum of 191.59 ms and a maximum of 222.86 ms. Zero packets were lost, while jitter reached 7.48 ms and the standard deviation was 7.91 ms.

This route ranks eighth among the 19 outbound paths measured from Melbourne and lands in the Fair latency tier. The measured spread is about 3.9% of the average, slightly above the network-wide median of 3.28%, so the delay profile is consistent but not exceptionally tight.

Miami's role as the digital gateway between North and South America makes it a distinct destination, but the physical distance of 15,591.9 km still dominates: the vacuum floor is 104.02 ms and the fiber floor is 152.69 ms. The observed average is 1.32 times the fiber floor, with 76% fiber efficiency, indicating the route carries more overhead relative to the theoretical minimum.

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: MEL → MIA

50 ICMP echo samples at 100 ms intervals · round 2026-08-16T04:07:28Z · avg 201.0 ± 1.12 ms (SE)

Sample distribution: box = interquartile range (195.2–204.4 ms), median 198.8 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 (152.7 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Melbourne (-37.81400, 144.96332) and Miami (25.77427, -80.19366). It does not disclose either facility address.

WGS-84 geodesic distance	15,591.9 km
Vacuum RTT floor	104.02 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	152.69 ms
Low-latency fiber material floor	152.07 ms
Engineering floor (5% path allowance)	160.34 ms
Research 1.33× mapped-fiber reference	203.07 ms
Estimated unamplified path loss	3274.3 dB
Transparent optical spans / inline amplifiers	205 / 204
Published RTT inflation over fiber floor	1.32×

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.
