Google has owned and invested in five private subsea cable systems. Junior cable is technically Google’s first private owned subsea cable.  But Junior cable is a domestic subsea cable connecting Rio de Janeiro to Santos in Brazil. CurieDunant, and Equiano and Grace Hopper are international cables. In many cases, only CurieDunant, and Equiano and Grace Hopper are mentioned as Google's private cables

Between 2016 and 2018, Google invested US$47 billion in capex to improve Google Cloud infrastructure which includes 134 points of presence (PoP) and 14 subsea cable investments globally.
