ICMP echo RTT measurements for Marseille, France, to Berlin, Germany, with average latency, packet loss, jitter, and fiber efficiency details.

🇫🇷 Marseille, France (MRS) → 🇩🇪 Berlin, Germany (BER)

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

On 2026-08-15T04:03:13Z, ICMP echo RTT from Marseille, France, to Berlin, Germany, averaged 21.5 ms across 50 samples, with a minimum of 20.57 ms and a maximum of 24.57 ms. The path carried all packets successfully, with 0% loss and jitter of 0.59 ms.

Using the network's 19 outbound routes as context, this route ranked 4th by median RTT. Its run-to-run variation was about 4.3% of the average, above the network-wide median variation of 3.08%; the gap between the 20.57 ms minimum and 24.57 ms maximum is small in absolute terms but noticeable relative to other fast routes.

The 1,187 km great-circle distance gives a fiber-floor estimate of 11.62 ms, so the measured 21.5 ms RTT is about 1.85 times that floor, or 54.1% fiber efficiency. This route covers the east–west corridor from the Mediterranean cable hub to Berlin with no loss and a low average, while the slightly wider timing spread means single-sample checks should expect occasional excursions toward the 24.57 ms maximum.

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 → BER

50 ICMP echo samples at 100 ms intervals · round 2026-08-15T04:03:13Z · avg 21.5 ± 0.13 ms (SE)

Sample distribution: box = interquartile range (20.9–21.9 ms), median 21.2 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 (11.6 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Marseille (43.29695, 5.38107) and Berlin (52.52437, 13.41053). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	1,187 km
Vacuum RTT floor	7.92 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	11.62 ms
Low-latency fiber material floor	11.58 ms
Engineering floor (5% path allowance)	12.21 ms
Research 1.33× mapped-fiber reference	15.46 ms
Estimated unamplified path loss	249.3 dB
Transparent optical spans / inline amplifiers	16 / 15
Published RTT inflation over fiber floor	1.85×

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.
