Nearly 200 government and business officials gathered Wednesday morning to celebrate the occasion at Google Fiber's newly opened facility, Fiber Space, a trendy customer-service center and internet cafe at Trolley Square mall.
"As of 9 a.m., Google Fiber is live in Salt Lake City," Scott Tenney, head of Google Fiber business operations in Utah, told the crowd.
The company simultaneously emailed thousands of prospective customers, saying access to its broadband capacity had arrived.
Tenney said in an interview that other parts of the city would be turned on "in a matter of months and not years." He declined to provide specifics.
"We're going everywhere as fast as we can," Tenney said. "This is a milestone, but not a destination."
A spokesman for first-term Mayor Jackie Biskupski said city officials were "very excited" about the launch, with its promise of boosting economic-development efforts and helping extend internet access to lower-income residents through Google Fiber's initiatives to address the "digital divide."
In that regard, Salt Lake City Council Vice Chairman Stan Penfold said Wednesday that the company had prioritized the west side in subsequent service launches.
In front of a phalanx of TV cameras, Salt Lake City Council member Derek Kitchen ran a test of Google Fiber's impressive data transfer speeds, first by downloading a feature-length high-definition movie, then uploading 100 photos — both in a matter of seconds.
When asked for his views on high-speed fiber optic web access, an awed Kitchen said: "To me, it's make-believe."
Google Fiber sales people highlighted the prospect of crystal-clear video and an end to competing with family members for bandwidth.
Google Fiber's parent company, Alphabet Inc., chose Salt Lake City in March 2015 after extensive courting by then-Mayor Ralph Becker and his staff. Utah's capital joined a list of nearly 25 U.S. cities where the service is live, under construction or in the planning stages, including Provo; Atlanta; Nashville and Chattanooga, Tenn; Kansas City, Mo.; and Austin, Texas.
The company will offer a slower Fiber 100 service of 100 megabits per second, or Mbps, for $50 a month, as well as its top-speed gigabit-per-second connection, called Fiber 1000, for $70 a month.
Customers can add a 220-channel TV package to Fiber 1000 — including high-definition service and a nearly 2 terabyte-capacity DVR — for a total tab of $140 a month. Some popular TV content — such as HBO and the Pac-12 Networks — is available at an added premium.
Phone service can also be had, for another $10 a month.
Small and medium-size businesses can pay $70 a month for 100 Mbps, $100 monthly for 250 Mbps speeds and $250 a month for gigabit speeds. Google Fiber does not yet offer an enterprise-level package to larger businesses, Tenney said.
