Paris, France to São Paulo, Brazil ICMP RTT measurement: average latency, jitter, packet loss, and route efficiency for the South Atlantic path.

🇫🇷 Paris, France (PAR) → 🇧🇷 São Paulo, Brazil (GRU)

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

For the 2026-08-16T04:07:28Z measurement round, ICMP echo RTT from Paris, France to São Paulo, Brazil averaged 175.8 ms across 50 samples, with a minimum of 173.09 ms and a maximum of 186.7 ms. No packets were lost, and jitter was 2.5 ms.

This route ranked 15th among 19 outbound routes measured from Paris, putting it in the lower portion of the set. Its standard deviation is 2.78 ms, about 1.6 percent of the average RTT, well below the 3.28 percent median relative variability; the higher latency is paired with consistent timing.

The great-circle distance is 9,377.8 km, and the mean RTT is about 1.91 times the estimated fiber floor, implying a fiber efficiency of 52.2%. That lower efficiency points toward a lengthier or less direct intercontinental crossing, though the zero-loss, low-jitter result shows the route remains stable at the network layer.

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 → GRU

50 ICMP echo samples at 100 ms intervals · round 2026-08-16T04:07:28Z · avg 175.8 ± 0.39 ms (SE)

Sample distribution: box = interquartile range (173.9–176.5 ms), median 175.0 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 (91.8 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Paris (48.85341, 2.34880) and São Paulo (-23.54750, -46.63611). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	9,377.8 km
Vacuum RTT floor	62.56 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	91.83 ms
Low-latency fiber material floor	91.47 ms
Engineering floor (5% path allowance)	96.44 ms
Research 1.33× mapped-fiber reference	122.14 ms
Estimated unamplified path loss	1969.3 dB
Transparent optical spans / inline amplifiers	124 / 123
Published RTT inflation over fiber floor	1.91×

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-gru.pings.{csv,json,yaml}.
