São Paulo to Los Angeles ping and RTT: 131.3 ms, 4.3 ms jitter, 96.89 ms fiber floor, and 73.8% efficiency across AS203314. Updated 2026-08-09.

🇧🇷 This page compares the published ping and round-trip time (RTT) from São Paulo (GRU) to 🇺🇸 Los Angeles (LAX) with vacuum and optical-fiber physical limits.

As of August 9, 2026, the São Paulo → Los Angeles route on Hats Network averages 131.3 ms RTT across a 50-sample daily ICMP echo measurement round, 1.36× the theoretical fiber-floor limit of 96.89 ms.

Among the 19 measured routes departing São Paulo, this route ranks 4th fastest by average RTT.

With a stdev-to-average ratio of 4.4%, this route fluctuates more than the network median of 3.4%, so short congestion windows can surface as transient RTT spikes. Across the round, per-probe RTT ranged from 125.81 ms to 161.06 ms with a standard deviation of 5.82 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 → LAX

50 ICMP echo samples at 100 ms intervals · round 2026-08-09 · avg 131.3 ± 0.82 ms (SE)

Sample distribution: box = interquartile range (127.5–133.3 ms), median 129.5 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 (96.9 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for São Paulo (-23.54750, -46.63611) and Los Angeles (34.05223, -118.24368). It does not disclose either facility address.

Vacuum RTT floor	66.01 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	96.89 ms
Low-latency fiber material floor	96.51 ms
Engineering floor (5% path allowance)	101.75 ms

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-lax.pings.{csv,json,yaml}. When citing, include the route, the measurement round date, and the dataset version — for example: "Hats Network latency dataset, São Paulo → Los Angeles round 2026-08-09, CC BY 4.0".
