ICMP round-trip latency from Amsterdam, Netherlands to Ashburn, USA: measured average, minimum, maximum, jitter, and packet loss for the Amsterdam–Ashburn route

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

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

In the 2026-08-15T04:03:13Z measurement round, the Amsterdam-to-Ashburn ICMP echo route averaged 75.7 ms round-trip time across 50 samples, with a minimum of 71.94 ms, a maximum of 87.08 ms, and no packet loss.

The 3.2 ms standard deviation and 2.62 ms jitter keep the RTT spread tight, and the average sits at 1.24 times the theoretical fiber floor for the 6,223 km distance, an 80.5% fiber efficiency figure. It remains within the Excellent latency tier.

Ranked 8th among the 19 Amsterdam outbound routes in this round, this path shows variation of roughly 4.2% of its average RTT, above the 3.08% median variation across those routes. Even so, the zero-loss sample and narrow absolute jitter make it a notably direct and steady transatlantic route.

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: AMS → IAD

50 ICMP echo samples at 100 ms intervals · round 2026-08-15T04:03:13Z · avg 75.7 ± 0.45 ms (SE)

Sample distribution: box = interquartile range (73.4–77.3 ms), median 74.8 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 Amsterdam (52.37403, 4.88969) and Ashburn (39.04372, -77.48749). 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

Transparent optical spans / inline amplifiers	82 / 81
Published RTT inflation over fiber floor	1.24×

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.
