Amazon Web Services (AWS) has announced plans to build a new transatlantic submarine cable to connect the United States to Ireland.

Scheduled to begin service in 2028, the route, dubbed Fastnet, will connect Maryland to Cork County and promises to provide more than 320 Tbps of capacity, which is equivalent to approximately 12.5 million HD streams or the transmission of the entire Library of Congress digitized three times per second.
