ICMP RTT measurement for Los Angeles, USA to Paris, France: average 135.4 ms, jitter 2.91 ms, zero packet loss, and distance-adjusted latency context.

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

Measurement round: 2026-08-15T04:03:13Z.

Measured in the 2026-08-15T04:03:13Z round, the Los Angeles-to-Paris path returned an average ICMP RTT of 135.4 ms, with a minimum of 131.38 ms and a maximum of 145.94 ms. All 50 samples reached the destination with zero packet loss, while jitter was 2.91 ms and standard deviation was 3.54 ms.

The great-circle distance of 9,107.2 km yields a vacuum-light floor of 60.76 ms and a fiber-floor estimate of 89.18 ms. The observed average is 1.52 times that fiber floor, or about 65.9% fiber efficiency, indicating that the path's extra delay is modest relative to the unavoidable distance bound.

Within the 19-route outbound set, this path ranks 10th by average RTT, placing it near the middle of the group. Its variability is below the route-set median of 3.08% when standard deviation is expressed relative to average, so the route offers a stable round-trip time. Paris's position as an interconnection market on the Northwest European corridor makes this measurement relevant for long-haul traffic into continental Europe.

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 2026-08-15T04:03:13Z · avg 135.4 ± 0.50 ms (SE)

Sample distribution: box = interquartile range (132.9–136.2 ms), median 134.5 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.

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

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.

Per-pair files are available at /opendata/latency/latest/pairs/lax-par.pings.{csv,json,yaml}.
