With Project Waterworth, we continue to advance engineering design to maintain cable resilience, enabling us to build the longest 24 fibre pair cable project in the world and enhance overall speed of deployment, wrote the Meta executives.The multibillion-dollar investment, which will see cables laid at depths of 7,000 meters, will take years to complete, but promises increased access to high-speed connectivity, which it said could, for example, support artificial intelligence (AI) innovation across the world.AI is revolutionising every aspect of our lives, from how we interact with each other to how we think about infrastructure and Meta is at the forefront of building these innovative technologies, the company said. As AI continues to transform industries and societies around the world, its clear that capacity, resilience and global reach are more important than ever to support leading infrastructure.Read more about subsea cablesVodacom lands 2Africa subsea cable in the Eastern Cape, South Africa: What is described as transformative subsea cable lands at the Vodacom facility in Gqeberha at South Africas Eastern Cape toprovide a gateway to direct international connectivity for faster, more reliable communications.RETN unveils new low latency London to Paris connectivity: International network services provider uses CrossChannel subsea cable to launch new low latency network route between London and Paris with a length of 550km.Grace Hopper subsea cable lands in UK: First private subsea cable to the UK funded by Google intended to improve diversity and resilience of the network, underpinning consumer and enterprise products, increasing capacity and powering services.Batelco claims Bahrain first with 400Ginternational capacity: Optical network technology supplier inks deal with leading telco provider in Bahrain to deliver 400G capacity high-speed connectivity as part of an initiative to upgrade internet service in the country.The blog post added: With Project Waterworth, we can help ensure that the benefits of AI and other emerging technologies are available to everyone, regardless of where they live or work.While subsea cables promise to enable global connectivity, there are concerns over how these costly and critical infrastructures can be protected from attacks from hostile states.MPs and peers recently launched an inquiry into the UKs ability to protect undersea internet cables that link the country with the rest of the world. This followed heightened threats of sabotage.The Joint Committee on the National Security Strategy, which scrutinises government decision-making on national security, aims to assess the UKs readiness for potential attacks on critical undersea communication cables.The inquiry followed astatement by defence secretary John Healey, warning that Russian president Vladimir Putin is targeting the UKs undersea oil, gas, electricity and internet cables after a Russian spy ship entered British waters.According to the parliamentary committee, 99% of the UKs data passes through undersea internet cables.As the geopolitical environment worsens, foreign states are seeking asymmetric ways to hold us at risk, said committee chairman Matt Western. Our internet cable network looks like an increasingly vulnerable soft underbelly. There is no need for panic we have a good degree of resilience, and awareness of the challenge is growing. But we must be clear-eyed about the risks and consequences: an attack of this nature would hit us hard.The global internet, which is critical for international communications and commerce, relies on a network of 500 cables that carry 95% of internet traffic. The cables are often in remote places, making them difficult and expensive to monitor.In The Current Issue:AI Action Summit: Global leaders decry AI red tapeNavigating the practicalities of AI regulation and legislationDownload Current Issue
