Google announced today an investment of $30 billion dollars to improve the infrastructure, from data centers to subsea cables. Google is adding three new submarine cables and five new regions in the next 3 years.
Google Cloud will open Netherlands and Montreal regions in the first quarter of 2018, followed by Los Angeles, Finland, and Hong Kong. Then, in 2019 Google will commission three subsea cables: Curie, a private cable connecting Chile to Los Angeles; Havfrue, a consortium cable connecting the U.S. to Denmark and Ireland; and the Hong Kong-Guam Cable system (HK-G), a consortium cable interconnecting major subsea communication hubs in Asia.
