# Marseille, France → Singapore RTT

🇫🇷 **Marseille, France (MRS)** → 🇸🇬 **Singapore (SIN)**

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

The Marseille-to-Singapore ICMP echo RTT path averaged 139.6 ms across 50 samples in round 2026-08-16T04:07:28Z, with a minimum of 132.36 ms and a maximum of 163.5 ms. No packets were lost, and the 4.16 ms jitter and 6.56 ms standard deviation point to a stable network path.

Marseille, France is a Mediterranean submarine cable landing hub, while Singapore, Singapore is Southeast Asia's interconnection center; this round-trip measurement spans about 10,598.5 km along the great-circle reference. The 139.6 ms average is 1.35 times the 103.79 ms fiber-floor estimate, so the route retains 74.3% fiber efficiency.

The route ranked 10th of 19 outbound paths measured in this round. Its standard deviation equals roughly 4.7% of the average RTT, slightly above the round's median standard-deviation-to-average ratio of 3.28%, but the absence of loss and the low jitter keep the overall latency tier at Good.

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