Paris to Melbourne ping and RTT: 243.4 ms, 8.99 ms jitter, 164.4 ms fiber floor, and 67.5% efficiency across AS203314. Updated 2026-08-09.

🇫🇷 This page compares the published ping and round-trip time (RTT) from Paris (PAR) to 🇦🇺 Melbourne (MEL) with vacuum and optical-fiber physical limits.

As of August 9, 2026, the Paris → Melbourne route on Hats Network averages 243.4 ms RTT across a 50-sample daily ICMP echo measurement round (source: GSL), 1.48× the theoretical fiber-floor limit of 164.4 ms.

Among the 19 measured routes departing Paris, this route ranks 18th fastest by average RTT.

With a stdev-to-average ratio of 3.6%, this route sits close to the network-wide stability median of 3.4%. Across the round, per-probe RTT ranged from 231.95 ms to 279.57 ms with a standard deviation of 8.82 ms.

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: PAR → MEL

50 ICMP echo samples at 100 ms intervals · round 2026-08-09 · avg 243.4 ± 1.25 ms (SE)

Sample distribution: box = interquartile range (237.3–248.1 ms), median 240.8 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 (164.4 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Paris (48.85341, 2.34880) and Melbourne (-37.81400, 144.96332). 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.

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/par-mel.pings.{csv,json,yaml}. When citing, include the route, the measurement round date, and the dataset version — for example: "Hats Network latency dataset, Paris → Melbourne round 2026-08-09, CC BY 4.0".
