# Amsterdam, Netherlands → Berlin, Germany RTT

🇳🇱 **Amsterdam, Netherlands (AMS)** → 🇩🇪 **Berlin, Germany (BER)**

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

In the 2026-08-16T04:07:28Z measurement round, ICMP echo probes between Amsterdam, Netherlands and Berlin, Germany averaged 7.2 ms over 50 samples, with a minimum of 6.88 ms and a maximum of 8.21 ms. No packets were lost, and jitter held at 0.23 ms, so the route was both fast and stable during the test window.

The physical reference for this 579.2 km great-circle route is a vacuum transit floor of 3.86 ms and a realistic fiber floor of 5.67 ms. The observed average latency is only 1.27 times the fiber floor, corresponding to 78.8% fiber efficiency and leaving little additional latency over the theoretical fiber minimum.

This path ranks fourth in a field of 19 outbound routes measured from Amsterdam in the same round. Its 0.31 ms standard deviation is about 4.3% of the 7.2 ms average, a touch above the 3.28% median standard-deviation-to-average ratio across the route set, but the absolute spread stays under a third of a millisecond.

## 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/ams-ber.pings.{csv,json,yaml}`. When citing, include the route, the measurement round timestamp, and the dataset version — for example: "Hats Network latency dataset, Amsterdam → Berlin round 2026-08-16T04:07:28Z, CC BY 4.0".
