The three will take to 11 the number of subsea cables that Google has been involved in building, according to The Wall Street Journal.
Other companies have built their own cables too: in September last year, Microsoft announced that it had completed construction of the Marea subsea cable, a joint project with Facebook and global telecommunications infrastructure company Telxius.
Ben Treynor, vice-president of Google’s cloud platform, told the newspaper that the only way to grow the company's cloud business was by creating more bandwidth.
The longest of the three new undersea cables will be a fully private link between Los Angeles and Chile, a distance of 9977 kms. Google has a data centre in Chile which was built in 2015. The cable has been named Curie after the French scientist Marie Curie.
A second cable, which will run from the US east coast to Denmark, with a stopover in Ireland, will be 7242 kms in length. The Havfrue — Danish for mermaid — will provide additional bandwidth over the Atlantic. Google will share capacity with Facebook on this cable.
The third cable, HK-G, will run for 3862 kms and link Hong Kong and Guam. It will have links to other cable systems that link Australia, East Asia and North America.
The three new cables will enable the linking of five new regions for cloud clients: Montreal, the Netherlands, Los Angeles, Finland and Hong Kong.
