ICMP RTT from São Paulo, Brazil to New York, USA: 122 ms average, 0% loss, stability details, and the route's rank among 19 measured routes.

🇧🇷 São Paulo, Brazil (GRU) → 🇺🇸 New York, USA (NYC)

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

In the 2026-08-15T04:03:13Z ICMP echo round, 50 probes from São Paulo, Brazil to New York, USA returned an average RTT of 122 ms, with a tight spread from 119.57 ms to 129.74 ms. Loss was 0%, jitter was 1.53 ms, and the standard deviation was 1.93 ms, keeping the connection in the good latency tier despite the distance.

The 7,657.6 km great-circle distance has a vacuum floor of 51.09 ms and a fiber floor of 74.99 ms. The measured 122 ms is 1.63 times the fiber floor, leaving a fiber efficiency of 61.5%, so the connection carries noticeable excess delay over the theoretical best case.

This route ranked second among the 19 outbound routes in the round, and its variability, at 1.58% of the average RTT, is well below the route-set median of 3.08%. The combination of zero packet loss and very low jitter makes the São Paulo–New York result notably stable for a route of this length.

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 → NYC

50 ICMP echo samples at 100 ms intervals · round 2026-08-15T04:03:13Z · avg 122.0 ± 0.27 ms (SE)

Sample distribution: box = interquartile range (120.7–122.5 ms), median 121.7 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 (75.0 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for São Paulo (-23.54750, -46.63611) and New York City (40.71427, -74.00597). It does not disclose either facility address.

WGS-84 geodesic distance	7,657.6 km
Vacuum RTT floor	51.09 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	74.99 ms
Low-latency fiber material floor	74.69 ms
Engineering floor (5% path allowance)	78.75 ms
Research 1.33× mapped-fiber reference	99.74 ms
Estimated unamplified path loss	1608.1 dB
Transparent optical spans / inline amplifiers	101 / 100
Published RTT inflation over fiber floor	1.63×

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