Ping Measurement Series
50 ICMP echo probes were recorded in this round. Individual replies and their distribution are shown below.
Ping series: FRA → GRU
50 ICMP echo samples at 100 ms intervals · round 2026-10-20T08:46:17Z · avg 181.6 ± 0.60 ms (SE)
Sample distribution: box = interquartile range (178.5–183.1 ms), median 180.4 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 (96.0 ms) for this route.

Theoretical Fiber Latency
The propagation model uses public city-centre coordinates from GeoNames: Frankfurt am Main (50.11552, 8.68417) and São Paulo (-23.54750, -46.63611). These are not facility coordinates or a surveyed cable path.
| Physical Reference | Value |
|---|---|
| WGS-84 geodesic distance | 9,807.7 km |
| Vacuum RTT floor | 65.43 ms |
| Standard fiber RTT floor () | 96.04 ms |
| Low-latency fiber material floor | 95.66 ms |
| Engineering floor (5% path allowance) | 100.86 ms |
| Research 1.33× mapped-fiber reference | 127.74 ms |
| Estimated unamplified path loss | 2059.6 dB |
| Transparent optical spans / inline amplifiers | 129 / 128 |
| Published RTT inflation over fiber floor | 1.89× |
The span count assumes 80 km optical spans. Attenuation is a power-loss term, not a propagation delay. See the model assumptions and equations.

About This Measurement
These ICMP measurements cover the two backbone endpoints. Access networks, routing policy and load can change an end user's result. A probe round is not an SLA.
