AT&T today launched its gigabit fiber Internet service in parts of Cupertino, California, but the price isn't as good as it is in cities where AT&T faces competition from Google Fiber.

Google Fiber and AT&T's U-verse with GigaPower compete head-to-head in Kansas City and Austin. In those cities, AT&T matches Google's $70-per-month price for gigabit service, as long as you opt in to a program that lets AT&T watch your Web browsing and serve up personalized ads.

But AT&T charges more when it doesn't have to compete against Google. In Cupertino, AT&T said today it will offer "Internet speeds up to 1Gbps starting as low as $110 a month, or speeds at 300Mbps as low as $80 a month, with a one-year price guarantee." Despite being $40 more than AT&T's price for the same gigabit service in Kansas City and Austin, the Cupertino offer still requires opting in to the Internet usage monitoring.

Google has tentative plans for fiber service in nearby San Jose but hasn't announced a decision yet.

In Dallas, another city where AT&T doesn't have to compete against Google, it charges $120 a month for gigabit service. (Correction: AT&T recently changed the price from $120 to $110 a month.)

In North Carolina, AT&T reportedly dropped pricing from $120 to $70 after Google announced plans to expand into that state.

AT&T's GigaPower is now available in seven metro areas nationwide; AT&T says it plans to bring the fiber service to another 10 metro areas and is exploring an additional eight for possible deployments.

AT&T CEO Randall Stephenson last year claimed the company would "pause" its fiber investments because of the Federal Communications Commission decision to regulate broadband service more forcefully. AT&T quickly backtracked and today said it is still "considering expanding its all-fiber network to up to 100 cities and municipalities across 25 markets."

AT&T also claims it needs federal approval of its purchase of DirecTV to further expand its fiber plans.

CenturyLink is expanding its gigabit fiber deployments with new plans for 505 multi-unit housing developments in Utah. Meanwhile, Google announced last week that it will bring its fiber service to Salt Lake City. Google Fiber also just filed a business registration in Colorado, though the company says it has no concrete plans for that state.

Verizon has more extensive fiber deployments than Google, AT&T, or CenturyLink but is done expanding.
