Frankfurt, Germany to Marseille, France ICMP RTT page: 50-sample latency, jitter, packet loss, and fiber efficiency for round 2026-08-15T04:03:13Z.

🇩🇪 Frankfurt, Germany (FRA) → 🇫🇷 Marseille, France (MRS)

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

For round 2026-08-15T04:03:13Z, the Frankfurt-to-Marseille route delivered an average ICMP echo RTT of 17.2 ms over 50 samples, with a minimum of 16.36 ms and a maximum of 19.64 ms. There was no packet loss.

The spread was wider: standard deviation 0.74 ms and jitter 0.62 ms amount to roughly 4.3% of the average RTT, above the 3.08% median variability for the 19 outbound routes in this round. Still, the route's 17.2 ms average ranks fifth among those outbound routes and remains within the ultra-low latency tier.

The 798.8 km geodesic distance sets a fiber floor near 7.82 ms, so the observed average is 2.2 times that minimum. Fiber efficiency of 45.5% places the route in a moderate-efficiency range for an ultra-low-latency connection.

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: FRA → MRS

50 ICMP echo samples at 100 ms intervals · round 2026-08-15T04:03:13Z · avg 17.2 ± 0.10 ms (SE)

Sample distribution: box = interquartile range (16.6–17.5 ms), median 17.0 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 (7.8 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Frankfurt am Main (50.11552, 8.68417) and Marseille (43.29695, 5.38107). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	798.8 km
Vacuum RTT floor	5.33 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	7.82 ms
Low-latency fiber material floor	7.79 ms
Engineering floor (5% path allowance)	8.21 ms
Research 1.33× mapped-fiber reference	10.4 ms
Estimated unamplified path loss	167.7 dB
Transparent optical spans / inline amplifiers	11 / 10
Published RTT inflation over fiber floor	2.2×

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.

The measurement round behind this page is published as open data under CC BY 4.0 in the Hats Network latency dataset. Per-pair files are available at /opendata/latency/latest/pairs/fra-mrs.pings.{csv,json,yaml}.
