The Federal Communications Commission (FCC) has proposed new regulations aimed at enhancing the oversight of undersea internet cables, crucial for global communications as they carry approximately 99% of international internet traffic. The new rules would require operators of submarine line terminal equipment to obtain licenses, marking a significant regulatory shift. Additionally, the FCC plans to expand restrictions on equipment deemed as national security risks, particularly focusing on technology from China and other foreign adversaries. These changes could favor major U.S. tech companies like Meta Platforms, Inc. and Alphabet Inc.'s Google, both of which are heavily invested in global cable networks that support cloud computing and rising internet traffic demands. The proposed measures also include stricter security requirements for companies seeking accelerated approvals for new cable systems, emphasizing safeguards against espionage and improved data protection. This initiative comes amid increasing concerns in Washington regarding the vulnerabilities of critical communication infrastructure.
