The EASSy project is an initiative to construct and operate a submarine fibre-optic cable along the east coast of Africa to connect 20 coastal and land-locked countries to each other and to the rest of the world. With a focus. The launch of 2Africa enables us to offer our customers seamless connection between Africa and Europe, together with our SEA-ME-WE 5 and AAE-1 subsea cable resources to further extend to Asia, which is an important milestone of our global development strategy,” said Jessica Gu, Director & Chief. The project concerns the deployment of fibre optics networks in regions of Eastern Africa where, either these kinds of networks are not available, or they are expensive and unreliable. In both cases, the development of digital services enabled by broadband access is limited. Liquid Dataport is a dedicated international wholesale division of Liquid.
