AT&T said Tuesday that it will bring super fast Internet connections to Atlanta, Sandy Springs, Decatur and Newnan, giving metro Atlanta the first broad commitment to offer residents and small businesses speeds 100 times faster than the average for American homes.

But in its initial announcement, AT&T didn’t offer any details about when it will offer the local service or how much it will charge. Nor did it indicate whether it will go into any of the eight other communities it had announced in April that it was considering for the service.

Google started the local race for possible widespread fiber-to-the-home connections when it announced earlier this year that it was considering going into nine local communities, including Atlanta and Decatur. Google had said it expected to make a decision later this year on which cities will get the service.

A short time later, AT&T announced its own list of communities around the nation and in Georgia where it said it might provide the service. AT&T’s Tuesday announcement is the first public commitment of either company to actually bring the service to metro Atlanta.
