# Los Angeles, USA → New York, USA RTT

🇺🇸 **Los Angeles, USA (LAX)** → 🇺🇸 **New York, USA (NYC)**

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

In round 2026-08-16T04:07:28Z, the ICMP echo RTT from Los Angeles, USA to New York, USA averaged 57.9 ms over 50 samples, with a minimum of 55.78 ms, a maximum of 62.74 ms, and zero packet loss.

The measured standard deviation of 1.33 ms and jitter of 1.19 ms are tight, placing this route's variability well below the 3.28% median for the 19-route set; its average latency ranks third in that set. The average RTT is 1.50 times the theoretical fiber floor, or 66.7% fiber efficiency.

The narrow min-max range and zero loss across all 50 samples reinforce a stable route; at 1.50x the fiber floor, the average RTT tracks closely to the theoretical limit for the 3,944 km distance.

## 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](/opendata/latency/). Per-pair files are available at `/opendata/latency/latest/pairs/lax-nyc.pings.{csv,json,yaml}`. When citing, include the route, the measurement round timestamp, and the dataset version — for example: "Hats Network latency dataset, Los Angeles → New York round 2026-08-16T04:07:28Z, CC BY 4.0".
