ICMP RTT measurements from Ashburn, USA to New York, USA: 6 ms average, 0% packet loss, and 0.19 ms jitter based on 50 probes.

🇺🇸 Ashburn, USA (IAD) → 🇺🇸 New York, USA (NYC)

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

For the 2026-08-16T04:07:28Z round, Ashburn-to-New York produced an average ICMP RTT of 6 ms from 50 samples, with a minimum of 5.77 ms and a maximum of 6.79 ms, plus zero packet loss and jitter of 0.19 ms.

At 350.8 km, the reference vacuum floor is 2.34 ms and the direct fiber floor is 3.44 ms. The observed 6 ms average runs 1.75 times the fiber floor, a fiber efficiency of 57.3 percent, placing the route well within ultra-low-latency territory for this distance.

This route ranks first among the 19 Ashburn outbound routes measured in the same round. Its standard deviation of 0.20 ms is only about 3.3 percent of the average, close to the 3.28 percent median relative variation across the route set, and the near-zero jitter reinforces how consistent the short trip is.

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: IAD → NYC

50 ICMP echo samples at 100 ms intervals · round 2026-08-16T04:07:28Z · avg 6.0 ± 0.03 ms (SE)

Sample distribution: box = interquartile range (5.9–6.1 ms), median 5.9 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 (3.4 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Ashburn (39.04372, -77.48749) and New York City (40.71427, -74.00597). It does not disclose either facility address.

Physical Reference	Value

Vacuum RTT floor	2.34 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	3.44 ms
Low-latency fiber material floor	3.42 ms

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