Ashburn to Los Angeles ping and RTT: 59.8 ms, 1.64 ms jitter, 35.84 ms fiber floor, and 59.9% efficiency across AS203314. Updated 2026-08-09.

🇺🇸 This page compares the published ping and round-trip time (RTT) from Ashburn (IAD) to 🇺🇸 Los Angeles (LAX) with vacuum and optical-fiber physical limits.

As of August 9, 2026, the Ashburn → Los Angeles route on Hats Network averages 59.8 ms RTT across a 50-sample daily ICMP echo measurement round (source: GSL), 1.67× the theoretical fiber-floor limit of 35.84 ms.

Among the 19 measured routes departing Ashburn, this route ranks 3rd fastest by average RTT.

With a stdev-to-average ratio of 2.8%, this route is more stable than the network median of 3.4%. Across the round, per-probe RTT ranged from 57.42 ms to 64.58 ms with a standard deviation of 1.68 ms.

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 → LAX

50 ICMP echo samples at 100 ms intervals · round 2026-08-09 · avg 59.8 ± 0.24 ms (SE)

Sample distribution: box = interquartile range (58.4–60.7 ms), median 59.7 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 (35.8 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Ashburn (39.04372, -77.48749) and Los Angeles (34.05223, -118.24368). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	3,660.1 km
Vacuum RTT floor	24.42 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	35.84 ms
Low-latency fiber material floor	35.7 ms
Engineering floor (5% path allowance)	37.64 ms
Research 1.33× mapped-fiber reference	47.67 ms
Estimated unamplified path loss	768.6 dB
Transparent optical spans / inline amplifiers	49 / 48
Published RTT inflation over fiber floor	1.67×

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/iad-lax.pings.{csv,json,yaml}. When citing, include the route, the measurement round date, and the dataset version — for example: "Hats Network latency dataset, Ashburn → Los Angeles round 2026-08-09, CC BY 4.0".
