Google Fiber announced today that it's considering bringing its ultra high-speed internet service to three more cities: Irvine, California; Louisville, Kentucky; and San Diego.

The company will work with local leaders in each city during the coming months to reach its decision. At the same time, Google Fiber is still considering bringing the its service to Portland, Oregon; Phoenix; and San Jose, California, a spokesperson said.

Google Fiber is already available in the Kansas City metro area; Provo, Utah; and Austin, Texas. Earlier this year the company announced plans to expand into Atlanta, Charlotte, Raleigh-Durham, and Nashville.

Google Fiber is one of the entities being spun out of Google as an independent business under the new holding company Alphabet as part of a reorganization announced last month.
