ICMP RTT measurements from Los Angeles, USA to Paris, France: average latency, jitter, packet loss, and route efficiency for round 2026-08-16T04:07:28Z.

🇺🇸 Los Angeles, USA (LAX) → 🇫🇷 Paris, France (PAR)

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

For the 2026-08-16T04:07:28Z round, ICMP echo requests from Los Angeles, USA to Paris, France averaged 135.9 ms over 50 samples taken at 100 ms intervals. The minimum RTT was 128.01 ms, the maximum was 155.68 ms, and packet loss was 0%.

The route's standard deviation of 6.27 ms and jitter of 6.02 ms put variability at 4.61% of the average, above the network median of 3.28%. It ranked 10th among 19 outbound routes in the same measurement network, placing it near the middle of the set.

Against the 9,107.2 km great-circle distance, the observed RTT is 1.52 times the theoretical fiber floor, or 65.6% fiber efficiency. The average still lands in the Good latency tier, making this round a practical reference for Paris-bound traffic from the West Coast and for separating distance-related delay from network overhead. It is a network-layer ICMP measurement, not an SLA and not a proxy for end-user application experience.

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: LAX → PAR

50 ICMP echo samples at 100 ms intervals · round 2026-08-16T04:07:28Z · avg 135.9 ± 0.89 ms (SE)

Sample distribution: box = interquartile range (131.7–137.7 ms), median 134.1 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 (89.2 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Los Angeles (34.05223, -118.24368) and Paris (48.85341, 2.34880). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	9,107.2 km
Vacuum RTT floor	60.76 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	89.18 ms
Low-latency fiber material floor	88.83 ms
Engineering floor (5% path allowance)	93.66 ms
Research 1.33× mapped-fiber reference	118.62 ms
Estimated unamplified path loss	1912.5 dB
Transparent optical spans / inline amplifiers	120 / 119
Published RTT inflation over fiber floor	1.52×

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.
