Melbourne, Australia to Paris, France latency report: ICMP echo round-trip time, packet loss, jitter, and fiber efficiency from the measurement round.

🇦🇺 Melbourne, Australia (MEL) → 🇫🇷 Paris, France (PAR)

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

Round 2026-08-15T04:03:13Z recorded an average ICMP echo RTT of 243.6 ms from Melbourne to Paris, based on 50 probes with no packet loss. The minimum was 232.82 ms and the maximum 280.25 ms, placing the route in the fair latency tier.

The observed average is 1.48 times the theoretical direct-fiber floor of 164.4 ms, yielding a fiber efficiency of 67.5%. Jitter of 8.23 ms and a standard deviation of 10.32 ms show a wider spread than the straight-line fiber ideal would suggest.

Across the 19 outbound routes from this Melbourne vantage point, the path ranked 13th by RTT, and its variability was about 4.2% of the average—above the median variability of 3.08% across the route set. This makes it a higher-variation, loss-free route for Australia-to-France round-trip timing.

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 → PAR

50 ICMP echo samples at 100 ms intervals · round 2026-08-15T04:03:13Z · avg 243.6 ± 1.46 ms (SE)

Sample distribution: box = interquartile range (236.0–249.0 ms), median 239.5 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 (164.4 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Melbourne (-37.81400, 144.96332) and Paris (48.85341, 2.34880). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	16,787.7 km
Vacuum RTT floor	112 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	164.4 ms
Low-latency fiber material floor	163.74 ms
Engineering floor (5% path allowance)	172.64 ms
Research 1.33× mapped-fiber reference	218.65 ms
Estimated unamplified path loss	3525.4 dB
Transparent optical spans / inline amplifiers	221 / 220
Published RTT inflation over fiber floor	1.48×

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.
