petabit undersea cable

Meta is building a transoceanic submarine cable capable of petabit-per-second speeds, intended to connect multiple continents. The project, shared by researcher Gabriele Romano, would rank among the largest private internet infrastructure efforts ever undertaken. Interest centres on how the cable could boost global bandwidth and what it signals about major tech firms building their own backbone networks rather than relying on telecom consortia.

A weekly tech roundup highlights eight developments spanning AI, cybersecurity, infrastructure and regulation. Among them: discounted access to AI tools being sold on the dark web at up to 97% off, raising concerns about unauthorised account resales, and plans for a new petabit-capacity undersea cable. The roundup asks readers which of the week's technology shifts matters most.
