Theoretical Fiber Latency
The public physical reference uses the GeoNames city centres for Ashburn (39.04372, -77.48749) and New York City (40.71427, -74.00597). It does not disclose either facility address.
| Physical Reference | Value |
|---|---|
| WGS-84 geodesic distance | 350.8 km |
| Vacuum RTT floor | 2.34 ms |
| Standard fiber RTT floor () | 3.44 ms |
| Low-latency fiber material floor | 3.42 ms |
| Engineering floor (5% path allowance) | 3.61 ms |
| Research 1.33× mapped-fiber reference | 4.57 ms |
| Estimated unamplified path loss | 73.7 dB |
| Transparent optical spans / inline amplifiers | 5 / 4 |
| Published RTT inflation over fiber floor | 1.75× |
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.
