Current coverage is the north side of Kansas City, a suburb of Provo, Utah, and part of Austin, TX. That's all. Google talks big, Google Fiber seems to be more about hype and politics than installation.

Verizon got a lot further with fiber-to-the-home, with coverage for about 12% of households in their territory, before they gave up on FIOS expansion. It wasn't making money.

Sonic.net makes money with their fiber to the home system, but they only have a few cities around Santa Rosa, CA installed, and are trying for three neighborhoods in San Francisco. Maybe it pays because they don't spend so much on PR.
