Google has invited cities in nine metro areas around the U.S. to work with the company to explore what it would take to bring them its gigabit Internet service. The company promises that people will be able to use its Google Fiber service to surf the Internet at 100 times the speeds of existing broadband services.

The company did not provide details on which cities will be able to benefit from Google Fiber internet connectivity, but mentioned Atlanta; San Jose, Calif.; Phoenix; Portland, Ore. and Salt Lake City.

Google plans to work on a study of local factors that could affect construction, like topography (e.g., hills, flood zones), housing density and the condition of local infrastructure. Meanwhile, cities will complete a checklist of items that will help them get ready for a project of this scale and speed. For example, they'll provide Google with maps of existing conduit, water, gas and electricity lines so that the search giant can plan where to place fiber.

Google Fiber is currently is available in Kansas City, Kan.; Kansas City, Mo. and Provo, Utah. It's also coming to Austin, Texas this year. Pricing for the service in the Kansas City metropolitan area is up to $120 a month.
