🇺🇸 Miami, USA (MIA) → 🇷🇺 Moscow, Russia (MOW)

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

Miami to Moscow averaged 145.5 ms across 50 replies. The observed range was 142.62 to 152.94 ms; these figures describe one probe round, not a long-term service target.

Standard deviation was 2.55 ms, or 1.8% of the average. This describes variation within the sample without identifying its cause.

Ping Measurement Series

50 ICMP echo probes were recorded in this round. Individual replies and their distribution are shown below.

Ping series: MIA → MOW

50 ICMP echo samples at 100 ms intervals · round 2026-08-16T04:07:28Z · avg 145.5 ± 0.36 ms (SE)

Sample distribution: box = interquartile range (143.8–146.2 ms), median 144.7 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 (90.5 ms) for this route.

Theoretical Fiber Latency

The propagation model uses public city-centre coordinates from GeoNames: Miami (25.77427, -80.19366) and Moscow (55.75204, 37.61781). These are not facility coordinates or a surveyed cable path.

Physical Reference	Value
WGS-84 geodesic distance	9,239.8 km
Vacuum RTT floor	61.64 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	90.48 ms
Low-latency fiber material floor	90.12 ms
Engineering floor (5% path allowance)	95.02 ms
Research 1.33× mapped-fiber reference	120.34 ms
Estimated unamplified path loss	1940.4 dB
Transparent optical spans / inline amplifiers	122 / 121
Published RTT inflation over fiber floor	1.61×

The span count assumes 80 km optical spans. Attenuation is a power-loss term, not a propagation delay. See the model assumptions and equations.
