The internet is a global service that allows you to connect and communicate with people around the world. One of the reasons you're able to do this is due to huge undersea cables used to connect countries and continents. One of these cables is Marea (Spanish for tide) which cost £10 million to install and is over 4,000 miles long. It's part of a joint project between Microsoft, Facebook and Telxius and connects the state of Virginia and Spain together,
Although the cable was installed in 2017 it recently broke a record for the highest data transfer rate. Its normal data transfer rate was 20 terabits per second but thanks to a new transfer method the cable recently saw a 20% increase in speed bringing the new transfer speed up to 24.2 terabits per second setting a new record.
