Traditionally, Google relied on parallel computing on commodity hardware but in 2005, started developing own designs, which were revealed in 2009. In the late 2010s, Google began to build its own private submarine communications cables. The first, named Curie, connects California with Chile and is to be completed in 2019.

In February 2010, Google announced the Google Fiber project, with experimental plans to build an ultra-high-speed broadband network for 50,000 to 500,000 customers in one or more American cities.[143][144] Following Google’s corporate restructure to make Alphabet Inc. its parent company, Google Fiber was moved to Alphabet’s Access division.
