#Underwater #cables are a vital piece of the #AI buildout and #internet — investment is booming
Over 95% of international data and voice call traffic travels through nearly a million miles of underwater communication cables.
Investment into new #subseacable projects is expected to reach around $13 billion between 2025-2027, almost twice the amount that was invested between 2022 and 2024, according to telecommunications data provider firm TeleGeography.

Meta accounts for 10% of all fixed and 22% of all mobile traffic and that stands to grow with its increased investment in AI. @Techcrunch reports that this has led to the company planning its own subsea cable extending round the world — a 40,000km project that could cost more than $10 billion. It could be years before it becomes fully operational thanks to the limited number of companies that can build the infrastructure. “There’s a real tight supply on cable ships,” said Ranulf Scarborough, a submarine cable industry analyst. “They’re expensive at the minute and booked out several years ahead. Finding the available resources to do it soon is a challenge.”

Behind Europe’s agenda for undersea internet cables.
Submarine cables account for the majority of the world’s internet traffic, but as concerns over malicious actors moving to cripple or interfere with internet infrastructure increase, the European Union has a number of its own projects underway, underpinned by hidden political dynamics.

Dublin has welcomed a new subsea telecoms cable connecting Ireland with Iceland.
The project is part of a broader strategy from Dublin to make Ireland a “Gateway to Europe” regarding these cables by acting as a link between Europe and North America.
The cable will, by extension, connect Ireland to Northern Europe via further subsea links between Iceland and Denmark.
