ICMP RTT measurement between New York, USA and Marseille, France: average, jitter, packet loss, and route stability for the 2026-08-16 round.

🇺🇸 New York, USA (NYC) → 🇫🇷 Marseille, France (MRS)

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

The 2026-08-16T04:07:28Z round from New York to Marseille recorded an 80.2 ms average ICMP echo RTT, with 0.0% packet loss across 50 samples. The minimum of 78.94 ms and maximum of 85.06 ms translate to a 1.32 ms standard deviation and 0.93 ms jitter, so the path remained stable at this latency level.

Relative to the 61.91 ms fiber-floor estimate for a 6,321.9 km route, the measured average is 30% above the floor, putting fiber efficiency at 77.2%. This route ranked 10th among 19 outbound routes from New York in this round, and its relative variability was below the 3.28% median for that outbound group.

The absence of loss and the tight delay spread are useful signs that the path was stable during the round. The 80.2 ms figure is a useful ICMP latency baseline for a Mediterranean landing route, but it should not be interpreted as a forecast of end-user application speed.

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: NYC → MRS

50 ICMP echo samples at 100 ms intervals · round 2026-08-16T04:07:28Z · avg 80.2 ± 0.19 ms (SE)

Sample distribution: box = interquartile range (79.3–80.6 ms), median 79.8 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 (61.9 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for New York City (40.71427, -74.00597) and Marseille (43.29695, 5.38107). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	6,321.9 km
Vacuum RTT floor	42.18 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	61.91 ms
Low-latency fiber material floor	61.66 ms
Engineering floor (5% path allowance)	65.01 ms
Research 1.33× mapped-fiber reference	82.34 ms
Estimated unamplified path loss	1327.6 dB
Transparent optical spans / inline amplifiers	83 / 82
Published RTT inflation over fiber floor	1.3×

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.
