Rumors about Google (GOOG) bringing its high-speed fiber network to Austin, Texas gained a little more steam over the weekend when unnamed sources told Austin-based station KVUE that Google would indeed announce plans to expand its fiber service to the city this week. And now Engadget has got hold of a leaked embargoed press release from the Gig.U initiative congratulating the city of Austin for getting hooked up with Google Fiber, thus making it the second city to have access to the service that first launched in Kansas City last year. Google Chairman Eric Schmidt late last year insisted that Google Fiber “isn’t just an experiment,” but rather “a real business” that the company is “trying to decide where to expand next,” so it’s not all that surprising that Google has decided to slowly roll it out to other markets.

UPDATE: Gig.U writes in to say that its press release was merely sent out to reporters as a dummy release in case Google did announce a Fiber expansion on Tuesday. The initiative says it has no direct knowledge of whether or not Austin will get Google Fiber.
