🇺🇸 New York, USA (NYC) → 🇫🇷 Paris, France (PAR)

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

Round 2026-08-16T04:07:28Z measured ICMP echo RTT from New York, USA to Paris, France at 68.9 ms on average, with a 67.48 ms minimum, 73.26 ms maximum, 1.31 ms standard deviation, and 1.05 ms jitter. All 50 samples were returned with zero packet loss.

The geodesic distance of 5,852.7 km implies a vacuum floor of 39.05 ms and a straight-line fiber floor of 57.31 ms. At 68.9 ms, the measured average is only 1.2 times that fiber floor, or 83.2% fiber efficiency, a strong result for a transatlantic route.

Within the round's 19 outbound routes, this path ranked 7th. Its standard deviation equals 1.90% of the average, comfortably below the 3.28% median variability, and the 1.05 ms jitter points to a very stable handoff. Given Paris's role as a dense interconnection market with national and pan-European fiber paths, this RTT is a clean benchmark for traffic crossing into France.

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: NYC → PAR

50 ICMP echo samples at 100 ms intervals · round 2026-08-16T04:07:28Z · avg 68.9 ± 0.19 ms (SE)

Sample distribution: box = interquartile range (67.9–69.4 ms), median 68.4 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 (57.3 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for New York City (40.71427, -74.00597) and Paris (48.85341, 2.34880). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	5,852.7 km
Vacuum RTT floor	39.05 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	57.31 ms
Low-latency fiber material floor	57.08 ms
Engineering floor (5% path allowance)	60.19 ms
Research 1.33× mapped-fiber reference	76.23 ms
Estimated unamplified path loss	1229.1 dB
Transparent optical spans / inline amplifiers	77 / 76
Published RTT inflation over fiber floor	1.2×

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