Measurement page for ICMP echo RTT from Paris, France, to Berlin, Germany: 15.5 ms average, 0% packet loss, stability details from 50 samples.

🇫🇷 Paris, France (PAR) → 🇩🇪 Berlin, Germany (BER)

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

The 2026-08-16T04:07:28Z round sent 50 ICMP echo requests from Paris, France, to Berlin, Germany and produced an average RTT of 15.5 ms, with a minimum of 14.87 ms and a maximum of 17.28 ms. Packet loss was 0% and jitter was 0.43 ms, indicating a consistent, lossless path over the sampling window.

The geodesic distance between the two cities is 880.6 km. Compared with a fiber-floor estimate of 8.62 ms, the measured average is 1.8 times higher, translating to a fiber efficiency of 55.6%; that still places the route in the ultra-low latency tier for this east–west European corridor.

This route ranked 5th among 19 outbound routes. Its standard deviation of 0.57 ms is 3.7% of the average, close to the median variability of 3.28% across the same route set. The main insight is that the RTT is tightly clustered around 15.5 ms, making that average a dependable reference for this ICMP measurement round.

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: PAR → BER

50 ICMP echo samples at 100 ms intervals · round 2026-08-16T04:07:28Z · avg 15.5 ± 0.08 ms (SE)

Sample distribution: box = interquartile range (15.1–15.8 ms), median 15.4 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 (8.6 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Paris (48.85341, 2.34880) and Berlin (52.52437, 13.41053). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	880.6 km
Vacuum RTT floor	5.87 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	8.62 ms
Low-latency fiber material floor	8.59 ms
Engineering floor (5% path allowance)	9.06 ms
Research 1.33× mapped-fiber reference	11.47 ms
Estimated unamplified path loss	184.9 dB

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/par-ber.pings.{csv,json,yaml}.
