ICMP RTT data for the São Paulo, Brazil to Paris, France route: average latency, packet loss, jitter, and stability from the GRU-PAR measurement round.

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

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

For the 2026-08-15T04:03:13Z round, ICMP echo RTT from São Paulo, Brazil to Paris, France averaged 179.4 ms, with a minimum of 168.71 ms and a maximum of 211.17 ms. Across 50 samples spaced 100 ms apart, packet loss was 0%, jitter was 7.08 ms, and the standard deviation was 8.64 ms, placing the result in the Fair latency tier.

The geodesic distance is 9,377.8 km, giving a theoretical vacuum round-trip floor of 62.56 ms and a practical fiber-optic floor of 91.83 ms. The measured average of 179.4 ms is 1.95 times that fiber floor, so the route realizes 51.2% of the ideal fiber-path efficiency.

Compared with other outbound paths from the same origin, this route ranks 7th of 19, and the median standard-deviation-to-average ratio across that set is 3.08%. In practical terms, the 179.4 ms average is a dependable ICMP RTT baseline for this city pair: low variability, no loss, and a spread between minimum and maximum of about 42 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: GRU → PAR

50 ICMP echo samples at 100 ms intervals · round 2026-08-15T04:03:13Z · avg 179.4 ± 1.22 ms (SE)

Sample distribution: box = interquartile range (172.2–184.1 ms), median 179.0 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 São Paulo (-23.54750, -46.63611) and Paris (48.85341, 2.34880). 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	1.95×

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