São Paulo, Brazil → New York, USA RTT

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

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

For the 2026-08-16T04:07:28Z round, ICMP echo RTT from São Paulo, Brazil to New York, USA averaged 122ms across 50 samples, ranging from 116.85ms to 132.54ms. The 3.8ms standard deviation and 3.62ms jitter are modest, and all probes were returned without loss.

The average sits 63% above the theoretical fiber floor of 74.99ms for the 7,657.6km great-circle distance, translating to a 61.5% fiber efficiency. This is a larger overhead than a near-optimal path would show, though the round-trip times remain consistent.

This path is ranked second among the 19 outbound routes in the round, and its variability ratio of about 3.1% falls below the network median of 3.28%. The zero-loss result and contained jitter make it a dependable reference for São Paulo-to-New York latency, with the extra distance overhead being the main separating factor from a tighter fiber-floor result.

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 (118.9–124.2 ms), median 121.0 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 (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.

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.
