New York, USA → São Paulo, Brazil RTT

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

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

The 2026-08-15T04:03:13Z measurement round returned an average ICMP echo RTT of 108.3 ms between New York, USA and São Paulo, Brazil, with a minimum of 103.08 ms and a maximum of 123.64 ms. All 50 samples were received, so packet loss was 0 percent, and the 3.43 ms jitter figure points to stable timing across the sample.

At a geodesic distance of 7,657.6 km, the round-trip vacuum floor is 51.09 ms and the round-trip fiber floor is 74.99 ms. The 108.3 ms round trip is 1.44 times the fiber floor, which puts fiber efficiency at 69.2 percent. The route carried a Good latency tier, and the large baseline component—the minimum RTT is only about 5 ms below the average—means most of the delay was present even in the fastest sample.

This route ranked 12th among 19 outbound routes in the measurement set, where the typical variability-to-average ratio was 3.08 percent. The observed standard deviation of 4.41 ms is about 4.1 percent of the 108.3 ms average, slightly above that typical figure yet still small in absolute terms. The practical takeaway is that New York–São Paulo latency is both moderate and consistent, with the fastest observed sample at 103.08 ms serving as a useful baseline.

Latency Summary

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.

Sample distribution: box = interquartile range (104.9–109.6 ms), median 107.2 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 New York City (40.71427, -74.00597) and São Paulo (-23.54750, -46.63611). It does not disclose either facility address.

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.
