Berlin, Germany to Paris, France: ICMP RTT latency, jitter, packet loss, and route efficiency from measurement round 2026-08-16T04:07:28Z

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

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

In round 2026-08-16T04:07:28Z, the Berlin-to-Paris ICMP echo measurements averaged 15.6ms across 50 samples, with the full run between 14.9ms and 17.81ms and no packet loss.

This route sits 4th among the 19 outbound paths measured from Berlin in the same round. Its standard deviation of 0.63ms is about 4% of the average, slightly above the 3.28% median standard-deviation-to-average ratio across the route set, so the path is stable but not the steadiest in the group.

Against the 880.6km great-circle distance, the observed RTT is 1.81 times the theoretical fiber-floor estimate of 8.62ms, equating to 55.3% fiber efficiency. For an ultra-low-latency route, the jitter of 0.52ms and zero loss leave little to fault.

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: BER → PAR

50 ICMP echo samples at 100 ms intervals · round 2026-08-16T04:07:28Z · avg 15.6 ± 0.09 ms (SE)

Sample distribution: box = interquartile range (15.2–15.9 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 Berlin (52.52437, 13.41053) and Paris (48.85341, 2.34880). 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
Transparent optical spans / inline amplifiers	12 / 11
Published RTT inflation over fiber floor	1.81×

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