About

Google Fiber is Alphabet's high-speed fiber-to-the-home internet service provider offering gigabit (1 Gbps) and multi-gig (2 Gbps, 5 Gbps) internet speeds at transparent pricing with no data caps — available in select US metropolitan markets including Austin, Kansas City, Nashville, Salt Lake City, and Raleigh-Durham. Launched in Kansas City in 2012 as a Google demonstration project challenging the cable duopoly, Google Fiber operates under Alphabet's Access division and serves as both a commercial ISP and an ongoing argument for what broadband competition can look like.
