Google has owned and invested in four private subsea cable systems. Junior cable is technically Google’s first private owned subsea cable. However, Junior cable is a domestic subsea cable connecting Rio de Janeiro to Santos in Brazil, it’s not an international subsea cable. So it's said in many articles that Google has invested in three private international subsea cables, i.e., CurieDunant, and Equiano.

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.
