# Paris, France → Singapore RTT

🇫🇷 **Paris, France (PAR)** → 🇸🇬 **Singapore (SIN)**

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

Measurement round 2026-08-16T04:07:28Z produced a Paris-to-Singapore ICMP RTT average of 150.3 ms from 50 samples, with a minimum of 144.03 ms and a maximum of 164.23 ms. Standard deviation was 4.53 ms, jitter was 4.83 ms, and packet loss remained at 0%.

The straight-line distance of 10,741.6 km corresponds to a theoretical fiber floor of about 105.19 ms, so the observed average is 1.43 times that floor and the path achieves 70% fiber efficiency. This leaves a relatively modest overhead of roughly 45 ms above the ideal fiber path, with the extra delay spread evenly enough to keep jitter below 5 ms.

Among the 19 Paris outbound routes in this round, Singapore ranked 12th, placing it near the middle of the distribution. Its relative variability of about 3.0% is below the 3.28% median stability ratio for the round, so this path is a steadier-than-median member of the current Paris outbound set despite its 150 ms absolute latency.

## 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/par-sin.pings.{csv,json,yaml}`. When citing, include the route, the measurement round timestamp, and the dataset version — for example: "Hats Network latency dataset, Paris → Singapore round 2026-08-16T04:07:28Z, CC BY 4.0".
