Ashburn, USA → Amsterdam, Netherlands RTT
Ashburn-to-Amsterdam ICMP RTT page: 50 echo samples from USA to Netherlands, with average, minimum, maximum, jitter, and packet loss.
🇺🇸 Ashburn, USA (IAD) → 🇳🇱 Amsterdam, Netherlands (AMS)
Measurement round: 2026-08-15T04:03:13Z.
The 2026-08-15T04:03:13Z round captured 50 ICMP echo replies between Ashburn, USA and Amsterdam, Netherlands, with an average RTT of 75.7 ms and a narrow spread from 73.24 ms to 82.29 ms. Jitter was 1.85 ms, standard deviation 1.9 ms, and packet loss was zero, placing the route in the Excellent latency tier.
Against the 6,223.2 km separation, the vacuum-floor reference is 41.52 ms and the fiber floor is 60.94 ms. The measured average sits 1.24 times above the fiber floor, translating to 80.5% fiber efficiency — the path is using most of the straight-line fiber potential.
This route ranked 6th among the 19 outbound paths in the same round, well above the midpoint, while the median standard-deviation-to-average ratio across all outbound paths was 3.08%. Its own 2.51% ratio is tighter than that median, so both the low average and the low spread contribute to the Excellent tier.

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 2026-08-15T04:03:13Z · avg 75.7 ± 0.27 ms (SE)
Sample distribution: box = interquartile range (74.1–77.0 ms), median 75.3 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 (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.

| Vacuum RTT floor | 41.52 ms |
| Standard fiber RTT floor () | 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 |

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.
