Miami (USA) to Los Angeles (USA) ICMP RTT: 50-sample latency, packet loss, jitter, and fiber efficiency for the 2026-08-16T04:07:28Z round.

🇺🇸 Miami, USA (MIA) → 🇺🇸 Los Angeles, USA (LAX)

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

For the 2026-08-16T04:07:28Z measurement round, ICMP echo RTT from Miami, USA, to Los Angeles, USA, averaged 56.8 ms across 50 samples, with a 2.11 ms standard deviation, 1.82 ms jitter, and no packet loss. The minimum was 54.44 ms and the maximum 64.31 ms, a spread of about 9.9 ms.

The geodesic distance of 3,764.3 km implies a round-trip vacuum floor of 25.1 ms and a fiber floor of 36.9 ms, placing the 56.8 ms average at 1.54 times the fiber floor and a 64.9% fiber efficiency figure.

This route ranks 3rd among the 19 outbound routes measured from Miami, and its standard-deviation-to-average ratio of about 3.7% is slightly above the network's median variability of 3.28%. While the typical latency is solid, the maximum observation of 64.31 ms shows the path can add roughly 8 ms beyond the average in this round, so latency budgets should include a modest cushion.

Key takeaway: Miami-to-Los Angeles delivered loss-free, sub-65 ms RTT in this measurement round, with efficiency that fits a coast-to-coast hop.

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: MIA → LAX

50 ICMP echo samples at 100 ms intervals · round 2026-08-16T04:07:28Z · avg 56.8 ± 0.30 ms (SE)

Sample distribution: box = interquartile range (55.4–57.6 ms), median 56.2 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 (36.9 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Miami (25.77427, -80.19366) and Los Angeles (34.05223, -118.24368). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	3,764.3 km
Vacuum RTT floor	25.11 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	36.86 ms
Low-latency fiber material floor	36.71 ms
Engineering floor (5% path allowance)	38.71 ms
Research 1.33× mapped-fiber reference	49.03 ms
Estimated unamplified path loss	790.5 dB
Transparent optical spans / inline amplifiers	50 / 49
Published RTT inflation over fiber floor	1.54×

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/mia-lax.pings.{csv,json,yaml}.
