ICMP RTT measurement for Ashburn, USA to Berlin, Germany: average 86.1 ms, 0% loss, 76.7% fiber efficiency. Route context and insights.

🇺🇸 Ashburn, USA (IAD) → 🇩🇪 Berlin, Germany (BER)

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

On 2026-08-16T04:07:28Z, ICMP echo probes from Ashburn, USA to Berlin, Germany returned an average RTT of 86.1 ms, with a minimum of 84.07 ms and a maximum of 94.45 ms over 50 samples. Packet loss was 0% and jitter was 1.6 ms, placing the route in the Good latency tier.

The physical reference for this 6,744.5 km path is a vacuum floor of 44.99 ms and a fiber floor of 66.05 ms. The observed average sits 1.30 times above the fiber floor, translating to 76.7% fiber efficiency — a solid outcome for the US-to-Germany distance and a clear step above the theoretical minimum.

Within the same set of 19 outbound routes, this path ranks 9th, putting it near the middle of the network's latency distribution. Its standard deviation of 2.05 ms is about 2.4% of the average, which is tighter than the network's median 3.28% variability, so the route's Good-tier timing is also consistent across the run.

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: IAD → BER

50 ICMP echo samples at 100 ms intervals · round 2026-08-16T04:07:28Z · avg 86.1 ± 0.29 ms (SE)

Sample distribution: box = interquartile range (84.9–86.9 ms), median 85.3 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 (66.0 ms) for this route.

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