Theoretical Fiber Latency
The public physical reference uses the GeoNames city centres for São Paulo (-23.54750, -46.63611) and Melbourne (-37.81400, 144.96332). It does not disclose either facility address.

|---|---|
| WGS-84 geodesic distance | 13,105.1 km |
| Vacuum RTT floor | 87.43 ms |
| Standard fiber RTT floor () | 128.34 ms |
| Low-latency fiber material floor | 127.82 ms |
| Engineering floor (5% path allowance) | 134.77 ms |
| Research 1.33× mapped-fiber reference | 170.69 ms |
| Estimated unamplified path loss | 2752.1 dB |
| Transparent optical spans / inline amplifiers | 173 / 172 |
| Published RTT inflation over fiber floor | 2.16× |
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. End-user latency also depends on local access networks, congestion, routing policy, and traffic engineering. Stability indicators are comparative estimates, and none of these values is an SLA.
