ICMP echo RTT measurement from Ashburn, USA to Frankfurt, Germany: 50 samples, 81.2 ms average latency, 0% loss, jitter and efficiency metrics.

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

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

During measurement round 2026-08-16T04:07:28Z, 50 ICMP echo probes from Ashburn, USA to Frankfurt, Germany returned an average round-trip time of 81.2 ms, with a minimum of 79.1 ms, a maximum of 86.57 ms, and no packet loss.

The route's 6,566 km geodesic span has a theoretical vacuum floor of 43.8 ms and a fiber floor of 64.3 ms; the observed 81.2 ms average is 1.26 times the fiber floor, corresponding to 79.2% fiber efficiency. This suggests a path that stays reasonably close to a great-circle fiber trajectory despite connecting two major hubs.

This route ranked eighth of the 19 outbound routes measured from Ashburn in the same round. Its standard deviation of 1.81 ms is 2.2% of the average, below the 3.28% median fluctuation ratio across the peer set, so the route paired a mid-pack ranking with notably stable timing.

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 → FRA

50 ICMP echo samples at 100 ms intervals · round 2026-08-16T04:07:28Z · avg 81.2 ± 0.26 ms (SE)

Sample distribution: box = interquartile range (80.0–81.9 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 Ashburn (39.04372, -77.48749) and Frankfurt am Main (50.11552, 8.68417). 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

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-fra.pings.{csv,json,yaml}.
