ICMP RTT measurement for Ashburn, USA to Amsterdam, Netherlands: average 75.2 ms, 0% loss, 81% fiber efficiency. Route context and insights.

🇺🇸 Ashburn, USA (IAD) → 🇳🇱 Amsterdam, Netherlands (AMS)

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

During the 2026-08-16T04:07:28Z ICMP echo round, Ashburn, USA to Amsterdam, Netherlands averaged 75.2 ms over 50 probes, with a minimum of 72.76 ms and a maximum of 84.12 ms. All probes were returned without loss, and jitter measured 1.77 ms, putting the route in the Excellent latency tier.

The physical reference for this 6,223.2 km path is a vacuum floor of 41.52 ms and a fiber floor of 60.94 ms. At 75.2 ms average, the route runs 1.23 times the fiber floor, yielding 81% fiber efficiency; that is a strong result for the distance and means the route is already close to its physical ideal.

This route ranks 6th among the 19 outbound routes in the same measurement set, placing it on the faster side of the network profile. Its standard deviation of 2.32 ms works out to about 3.1% of the average, essentially matching the network's median 3.28% variability, so the excellent speed is accompanied by steady probe-to-probe behavior.

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 → AMS

50 ICMP echo samples at 100 ms intervals · round 2026-08-16T04:07:28Z · avg 75.2 ± 0.33 ms (SE)

Sample distribution: box = interquartile range (73.6–75.9 ms), median 74.6 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 (60.9 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Ashburn (39.04372, -77.48749) and Amsterdam (52.37403, 4.88969). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	6,223.2 km
Vacuum RTT floor	41.52 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	60.94 ms
Low-latency fiber material floor	60.7 ms
Engineering floor (5% path allowance)	64 ms
Research 1.33× mapped-fiber reference	81.05 ms
Estimated unamplified path loss	1306.9 dB
Transparent optical spans / inline amplifiers	82 / 81
Published RTT inflation over fiber floor	1.23×

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.

Per-pair files are available at /opendata/latency/latest/pairs/iad-ams.pings.{csv,json,yaml}.
