Global network latency test
Measure your latency to cloud regions and services spread across the world, and see which parts of the map are close, which are far and which are slower than they should be.

The map of how far things are
Distance sets a minimum: a signal in fiber needs about five milliseconds for every thousand kilometres, one way, and real routes are longer than straight lines. So a region on another continent will always be slower than one next door. The question is whether it is slower than it should be.
This test measures the destinations in the Cloud category, which are spread over several regions, and shows each one next to the world average. Open the live map to see the same destinations placed where they are.
What it is good for
- Choosing a cloud region for a service, based on the latency you really get, not on a map.
- Understanding why a remote service or colleague feels slow.
- Spotting a destination that is much worse than the rest, which usually means a routing problem and not just distance.
What it does not cover
The test measures public destinations, not internet exchange points or individual carrier networks, and it does not show the route your traffic takes. For that you would use a traceroute. What it gives you is the result that matters for users: how long it really takes to get an answer from there.
Questions
Why are far regions so much slower?
Because of distance and the route. Fiber carries light at about two thirds of its speed in a vacuum, and cables rarely run in a straight line.
Is the world average a fair comparison?
It is built from the tests of other visitors to the same destination, so it shows what is normal for each destination, and a far region compared with a far region.
Can I save or share the result?
Yes. A finished test creates a report link you can share, which contains only GlobeLatency destinations.
