Undersea Cable Map

The submarine cable network that carries the world’s internet — mapped and monitored.

Over 95% of intercontinental data travels through submarine cables. The Overseer maps this critical backbone so you can see the physical routes behind the global internet and the chokepoints where they cluster.

Overlay live internet-outage data and infrastructure layers to connect cable geography with connectivity disruptions as they unfold.
