What happened?
Amazon officially announced on September 16, 2026, that AWS will build Fastnet, a high-capacity transatlantic subsea cable connecting the United States and Ireland. The project is not a change to Amazon seller policies, FBA fees, or inbound requirements, and therefore will not directly change seller fees, fulfillment costs, or inbound requirements. The announcement primarily reflects Amazon’s continued efforts to strengthen data, cloud-service, and digital-infrastructure connectivity between the United States and Europe. Over the longer term, it could support inventory management, order synchronization, advertising systems, AI-based product analysis, and customer service. Sellers should not adjust pricing or promise faster delivery times based on this announcement. Brands that rely on Amazon advertising, APIs, ERP synchronization, cloud-based customer service, and European marketplace operations can view it as a signal of continued platform infrastructure investment.
What does this mean for cross-border sellers?
The Fastnet project will not change seller fees, FBA fees, fulfillment costs, or inbound requirements in the short term. Do not adjust prices or promise faster delivery based on it. Brand sellers relying on Amazon advertising, APIs, ERP synchronization, cloud-based customer service, or European marketplace operations should treat it as a signal of continued infrastructure investment and first optimize existing workflows.
