Summary
Amazon has initiated its first solo undersea project, the Atlantic Fastnet Cable, which will enhance its data center capabilities in Maryland and Southern Ireland. With a capacity of 320 Tbps, this new submarine cable reflects Amazon's strategic focus on resiliency over latency. The cable marks significant milestones, being the first in a decade to reach Ireland and the first ever to land in Maryland. Scheduled for RFS in 2028, it emphasizes the importance of geographical redundancy in data transmission for hyperscalers.
