Marseille, France to Miami, USA ICMP RTT measurement: 111.5 ms average, 5.49 ms jitter, zero packet loss, based on 50 samples.

🇫🇷 Marseille, France (MRS) → 🇺🇸 Miami, USA (MIA)

Measurement round: 2026-08-15T04:03:13Z.

For the 2026-08-15T04:03:13Z measurement round, the Marseille-to-Miami path delivered an average RTT of 111.5 ms over 50 ICMP samples. The minimum was 104.03 ms, the maximum 127.68 ms, and the zero packet loss adds confidence that the route remained usable for the full window.

Over a geodesic distance of 7,752.4 km, the observed average sits 1.47 times above the fiber-floor estimate of 75.92 ms, yielding a fiber efficiency of 68.1 percent. Given Marseille's role as a Mediterranean cable-landing hub and Miami's position as the NAP of the Americas convergence point, this is a plausible long-haul profile for traffic between Europe and Latin America-facing infrastructure.

Within the outbound context, the route ranks 9th out of 19 routes leaving Marseille, and the reference median variability for that set is 3.08 percent. The route's own standard deviation is 5.34 ms, or about 4.8 percent of the average, so the path is steady but slightly less consistent than the median profile.

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: MRS → MIA

50 ICMP echo samples at 100 ms intervals · round 2026-08-15T04:03:13Z · avg 111.5 ± 0.76 ms (SE)

Sample distribution: box = interquartile range (107.9–113.3 ms), median 110.7 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 (75.9 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Marseille (43.29695, 5.38107) and Miami (25.77427, -80.19366). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	7,752.4 km
Vacuum RTT floor	51.72 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	75.92 ms
Low-latency fiber material floor	75.61 ms
Engineering floor (5% path allowance)	79.72 ms
Research 1.33× mapped-fiber reference	100.97 ms
Estimated unamplified path loss	1628 dB
Transparent optical spans / inline amplifiers	102 / 101
Published RTT inflation over fiber floor	1.47×

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 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.
