Paris to Ashburn ICMP RTT statistics: 75.5 ms average latency from France to Virginia, USA, with packet loss and stability metrics.

🇫🇷 Paris, France (PAR) → 🇺🇸 Ashburn, USA (IAD)

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

The 2026-08-16T04:07:28Z round of 50 ICMP probes from Paris to Ashburn returned a 75.5 ms average RTT, a 2.46 ms standard deviation, and 2.26 ms jitter. No packets were lost, and the fastest reply came in at 72.75 ms while the slowest reached 85.2 ms.

That result placed the route eighth among the 19 outbound paths measured from Paris in this round. Its run-to-run spread worked out to about 3.26 percent of the average, slightly below the 3.28 percent median variability across the measured routes, so timing on the transatlantic leg stayed unusually consistent.

For a 6,202 km great-circle distance, the average sits roughly 15 ms above the 60.73 ms fiber lower bound, an inflation factor of 1.24 that corresponds to about 80 percent fiber efficiency. The zero-loss sample and narrow min-max range make this a notably stable path into the Northern Virginia corridor.

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: PAR → IAD

50 ICMP echo samples at 100 ms intervals · round 2026-08-16T04:07:28Z · avg 75.5 ± 0.35 ms (SE)

Sample distribution: box = interquartile range (73.7–76.5 ms), median 74.9 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 (60.7 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Paris (48.85341, 2.34880) and Ashburn (39.04372, -77.48749). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	6,202 km
Vacuum RTT floor	41.38 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	60.73 ms
Low-latency fiber material floor	60.49 ms
Engineering floor (5% path allowance)	63.78 ms
Research 1.33× mapped-fiber reference	80.78 ms
Estimated unamplified path loss	1302.4 dB
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.

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/par-iad.pings.{csv,json,yaml}.
