# Marseille, France → Berlin, Germany RTT

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

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

During the 2026-08-16T04:07:28Z ICMP echo round, Marseille-to-Berlin recorded an average RTT of 20.6 ms, a minimum of 19.99 ms, and a maximum of 21.74 ms across 50 samples. Packet loss was 0% and jitter was 0.3 ms, placing the route in the 'Ultra-Low' latency tier.

The route spans about 1,187 km in a straight line, corresponding to a 7.92 ms vacuum floor and an 11.62 ms fiber floor. Measured RTT comes in at 1.77 times the fiber floor, yielding roughly 56.4% fiber efficiency; that is a tighter fit to the theoretical floor than the distance alone would suggest.

Within the 19 outbound routes measured from Marseille in this round, this path ranked 5th by average RTT, putting it near the faster end of the group. Its standard deviation of 0.35 ms is about 1.70% of the average, well below the outbound group's median variability of 3.28%.

The standout feature of this round is consistency: the spread between minimum and maximum RTT is only 1.75 ms, and jitter is extremely low. For a link of nearly 1,200 km, the 20.6 ms average is remarkably steady, making this route one of the more predictable outbound paths from Marseille in the 2026-08-16T04:07:28Z measurement set.

## 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](/opendata/latency/). Per-pair files are available at `/opendata/latency/latest/pairs/mrs-ber.pings.{csv,json,yaml}`. When citing, include the route, the measurement round timestamp, and the dataset version — for example: "Hats Network latency dataset, Marseille → Berlin round 2026-08-16T04:07:28Z, CC BY 4.0".
