AWS is building a new high-speed subsea internet cable to connect the US and Ireland

• Fastnet will connect the US with Ireland, with over 320 Tbps of capacity
• AWS will bury it 1.5m under the seabed to protect it from damage
• More AWS Regions and Availability Zones are in the works

Amazon Web Services (AWS) has announced plans to build a new transatlantic subsea cable to connect the US with Ireland.

Expected to go live in 2028, the route, subbed Fastnet, will connect Maryland with County Cork, and promises to deliver over 320 Tbps of capacity, which equals roughly 12.5 million HD streams or transmitting the entire digitized Library of Congress three times per second.

AWS sees Fastnet as a new option to expand on its largely east coast-dominant cable networks, where it will act as a backup to reduce risks from accidental cuts or intentional sabotage.
