Frankfurt to Ashburn ICMP RTT measurement: average latency 81.5 ms, jitter, packet loss, and route efficiency from Germany to USA.

🇩🇪 Frankfurt, Germany (FRA) → 🇺🇸 Ashburn, USA (IAD)

Measurement round: 2026-08-15T04:03:13Z.

In the 2026-08-15T04:03:13Z measurement round, 50 ICMP echo requests from Frankfurt, Germany to Ashburn, USA produced an average round-trip time of 81.5 ms; the minimum was 78.04 ms, the maximum 93.26 ms, and packet loss was zero. The 2.04 ms jitter places the route in the good latency tier for a transatlantic distance.

The 6,566 km separation gives a vacuum floor of 43.8 ms and a fiber-floor estimate of 64.3 ms. The measured average is 1.27 times the fiber floor, a fiber efficiency of 78.9%, which is relatively close to the geometric ideal for such a long crossing and indicates little excess delay beyond the physical minimum.

This route is ranked eighth among the 19 outbound paths tracked in the same round. Its standard deviation of 3.14 ms is about 3.9% of the average, slightly above the network-wide median variability ratio of 3.08%, so the delay spread is a bit wider than typical even though packet loss is zero and fiber efficiency is strong.

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: FRA → IAD

50 ICMP echo samples at 100 ms intervals · round 2026-08-15T04:03:13Z · avg 81.5 ± 0.44 ms (SE)

Sample distribution: box = interquartile range (79.6–82.6 ms), median 80.7 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 (64.3 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Frankfurt am Main (50.11552, 8.68417) and Ashburn (39.04372, -77.48749). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	6,566 km
Vacuum RTT floor	43.8 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	64.3 ms
Low-latency fiber material floor	64.04 ms
Engineering floor (5% path allowance)	67.52 ms
Research 1.33× mapped-fiber reference	85.52 ms
Estimated unamplified path loss	1378.9 dB
Transparent optical spans / inline amplifiers	87 / 86
Published RTT inflation over fiber floor	1.27×

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.
