Where does my request go?

Type a website. We will draw the path your request takes across the ocean floor: cables, landing stations, kilometres and milliseconds, and what would change if one of those cables broke.

The path

FromToCablekmms

If a cable on this path breaks

The path is typical for your country and network, built from our own measurements and our graph of 728 cables and 1948 landing stations. Your provider may route differently. Distances are along cable routes; latency is one round trip. We do not know cable capacities, so we count paths and milliseconds, not traffic.

How this works

Where do the measurements come from?
From our own observation points in several countries that continuously trace routes to thousands of network nodes and cable landing stations. We do not use third-party monitors.
Why is the speed of light involved?
Light in optical fibre travels about 200 km per millisecond. Comparing the straight-line distance with the measured round trip shows how direct your route is.
What does "if a cable breaks" mean?
We remove that cable from our graph and compute the next shortest path by latency. The number is the extra delay by physics alone; real detours depend on contracts and capacity, which we do not model.
