Utopia said it is now testing what appears to be the first gigabyte (1000 Mbps) residential broadband service.

The Utah Telecommunications Open Infrastructure Agency (Utopia), which operates a municipal fiber-to-the-premises network, said it is now actually providing a 100 Mbps symmetrical broadband service. To a single customer. So far.

The customer, who resides in Layton, Utah, is getting service through Idaho-based FuzeCore, one of the service providers participating in the Utopia network.

FuzeCore's 100 Mbps service is available for $147 per month and offers a dedicated 100 Mbps downstream and 100 Mbps upstream.

By way of comparison, Cablevision said it will charge $99 per month for its new 101 Mbps service (story here), and Shaw Communications was charging $250 per month when it introduced its 100 Mbps service a couple of months ago (story here).

The Utopia network, owned by a group of 16 Utah cities, provides physical fiber-optic infrastructure directly to customers’ homes . Private-sector companies use the network to provide Internet, phone, video and other broadband services to business and residential customers.
