New undersea cable cutter risks Internet’s backbone
Summary
A Chinese test of a deep-sea cable-cutter demonstrates a new dual-use tool capable of severing submarine data cables thousands of meters underwater. The article frames this as a potential risk to the Internet’s backbone amid a rise in suspected sabotage incidents targeting undersea cables, highlighting the technical design (electro-hydrostatic actuator and diamond-coated grinding wheel) and the broader security and geopolitical implications, including Taiwan and global submarine infrastructure vulnerabilities.
