Amazon Web Services (AWS) has announced a new state-of-the-art transatlantic subsea fiber optic cable system connecting Co Cork to Maryland in the US.
AWS said that when operational in 2028, the Fastnet subsea cable will create alternative data pathways between delivering fast and reliable cloud and AI services across the Atlantic.
"Fastnet will add vital diversity for customers by building a new data pathway with unique landing points, keeping services running even if other undersea cables encounter issues," AWS said.
"This enhanced network resilience will improve global connectivity and meet rising demand for cloud computing and artificial intelligence (AI)," it added.
Fastnet is designed with two strategic landing points that deliver route diversity away from traditional cable corridors, which AWS said will strengthen the network by providing backup routes if other cables encounter issues.
AWS said the system could transmit the entire digitised US Library of Congress three times every second, or stream 12.5 million HD films simultaneously.
"Amazon's new Fastnet transatlantic subsea cable represents a vote of confidence in Ireland’s digital future, helping to enable the next wave of innovation in cloud computing and artificial intelligence," said Taoiseach Micheál Martin.
"By linking Co Cork to Maryland in the US, Ireland will become a true gateway to Europe for submarine telecommunications cables," he said.

"This investment will enhance our global connectivity, reinforce the resilience of critical digital infrastructure, and strengthen our economic competitiveness," Mr Martin said.
Wes Moore, Governor of Maryland, also welcomed the announcement.
"To grow our economy, we need to prioritise industries of the future," Mr Moore said.
"That is exactly what this project helps us deliver, in partnership with leaders with deep local ties and robust commitment to community engagement," he added.
