# Frankfurt, Germany → Paris, France RTT

🇩🇪 **Frankfurt, Germany (FRA)** → 🇫🇷 **Paris, France (PAR)**

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

The 2026-08-16T04:07:28Z ICMP echo round from Frankfurt, Germany to Paris, France recorded an average RTT of 7.6 ms across 50 samples, with a minimum of 7.34 ms, a maximum of 8.24 ms, and zero packet loss.

With 0.15 ms jitter and a 0.23 ms standard deviation, the measurements cluster tightly around the average. The observed RTT is 1.62 times the theoretical fiber floor of 4.7 ms for the 479.9 km distance, so the route sits close to the lower bound of what a straight fiber path would allow.

The same round covers 19 routes from this network, with Frankfurt-Paris ranking third. Its variability is about 3.0% of the average RTT, just under the network's median variability of 3.28%, which aligns with an ultra-low-latency result and no packet loss.

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