Google has announced plans to build a new undersea network cable connecting the US, UK and Spain.
The tech giant says it is incorporating new technology into the cable, which it claims is a significant upgrade to older existing lines.
The project is expected to be completed by 2022.
Underwater data cables are vital to global communications infrastructure, carrying some 98% of the world's data, according to Google's estimate.
The cables are usually built by communications firms - typically a group of them pooling resources - which then charge other companies to use them.
The latest cable, named "Grace Hopper" after an American computer scientist and naval rear admiral, will hit the UK at Bude, in Cornwall. It is Google's fourth privately owned undersea cable.
