Sydney to São Paulo ping and RTT: 293.8 ms, 9.87 ms jitter, 131 ms fiber floor, and 44.6% efficiency across AS203314. Updated 2026-08-09.

🇦🇺 This page compares the published ping and round-trip time (RTT) from Sydney (SYD) to 🇧🇷 São Paulo (GRU) with vacuum and optical-fiber physical limits.

As of August 9, 2026, the Sydney → São Paulo route on Hats Network averages 293.8 ms RTT across a 50-sample daily ICMP echo measurement round, 2.24× the theoretical fiber-floor limit of 131 ms.

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

With a stdev-to-average ratio of 3.7%, this route sits close to the network-wide stability median of 3.4%. Across the round, per-probe RTT ranged from 280.93 ms to 338.72 ms with a standard deviation of 10.92 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: SYD → GRU

50 ICMP echo samples at 100 ms intervals · round 2026-08-09 · avg 293.8 ± 1.54 ms (SE)

Sample distribution: box = interquartile range (287.1–296.6 ms), median 291.4 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 (131.0 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Sydney (-33.86785, 151.20732) and São Paulo (-23.54750, -46.63611). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	13,377 km
Vacuum RTT floor	89.24 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	131 ms
Low-latency fiber material floor	130.47 ms
Engineering floor (5% path allowance)	137.57 ms
Research 1.33× mapped-fiber reference	174.23 ms
Estimated unamplified path loss	2809.2 dB
Transparent optical spans / inline amplifiers	176 / 175
Published RTT inflation over fiber floor	2.24×

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