For more than 20 years there was no practical direct data transfer routes between Europe and South America. The only cable linking the two continents was Atlantis-2, which was not used for internet data transfer due to its limited capacity.[2]

One of the project's goal is to circumvent the United States as route to connect with Europe, due to the power this man-in-the-middle position gives to spy Brazilian communications by intelligence agencies, such as the National Security Agency.[3] In that regard, the then President of Brazil, Dilma Rousseff, said the EllaLink would be central to "ensure the neutrality" of the internet, showing her wish to block Brazilian internet traffic against US vigilance.[4]


The cable was launched 1 June 2021, providing a direct data route between Portugal and Brazil.[5]

AwardsEdit

EllaLink has received a Global Carrier Award in the category "Best Subsea Project of the Year".[6]

HistoryEdit

As of 06:19, Saturday, October 23, 2021 (UTC)

EllaLink was formed in 2012. The project began in 2015. In 2017, the supply contract was awarded to Alcatel Submarine Networks.[7] The equity provider Marguerite became the sponsor in 2018.[8]

Cable manufacture began in 2019[9] and installation of the cable was started in December 2020.[10] Two vessels (Ile de Brehat and Ile de Sein) were used to lay down the cable and its branching units. The installation of the cable was finished on February 28, 2021. The vessel Ile de Sein laid down the last universal cable joint linking together the Brazilian branch left by Ile de Brehat on February 1, 2021 and the European branch.[11][12]
