Google Fiber is live in Salt Lake City and ready to serve the internet needs of Utah's capital.

The web giant made the announcement Tuesday in a tweet that invited residents to check whether the super-high-speed Internet and TV services are available at their address and sign up for service. One gigabit service will run $70 per month, while 100 Mbps service will cost $50 per month -- both without data caps. TV and phone service cost extra.

Google Fiber is the company's attempt to shake up internet access in the United States, which Ookla ranks 27th across the world in terms of Internet speeds. Google's goal is to create faster Internet performance for consumers and businesses -- and ultimately to boost its profits. Google also hopes the service will spur innovation among people who find unique ways to use the high-speed network.

At 1 gigabit per second -- or 1,000 megabits per second -- Google Fiber is blazingly faster than the average Internet connection. The average broadband speed in the US is 34 megabits per second, according to Ookla.
