Plans for Google Fiber super-fast internet service are officially suspended in “most” of the cities where the service isn’t already operating or under construction, including San Jose and four other Silicon Valley cities.

Included under the San Jose category for Google Fiber are Santa Clara, Sunnyvale, Mountain View and Palo Alto. Local officials from San Jose and the other Silicon Valley cities had been working with Google Fiber on plans for networks.

Planning in San Jose had advanced to the point that Google Fiber had in May received final permits for a three-year construction project, to start two months later in July.

Job losses are coming, but it’s unclear how many employees will be moved within Alphabet.

“In this handful of cities that are still in an exploratory stage, and in certain related areas of our supporting operations, we’ll be reducing our employee base,” Craig Barratt, CEO of Access, the Alphabet division that handles Google Fiber, said in a blog post Tuesday.

Barratt didn’t specify which of the eight “potential” Fiber cities were among the “most” to have their ultra-high-speed-internet dreams stymied. Given the company’s clawback of scope for Google Fiber, officials from the cities will no doubt be asking Alphabet whether “most” means “all,” and if not, whether they still have a shot at Fiber.

But Barratt didn’t shut the door on ultra-high-speed service for those cities. Alphabet has been exploring wireless solutions to the connectivity problem.

“We’re confident we’ll have an opportunity to resume our partnership discussions once we’ve advanced our technologies and solutions,” he said.

Mercury News reporter Ramona Giwargis revealed in August that Google Fiber had been put on hold in San Jose and other cities, but the company didn’t confirm it at the time.

Barratt, in his post, also announced his resignation from Access, but said Alphabet CEO Larry Page had asked him to stay on as an adviser, so he’d be “around.”

The outgoing executive didn’t specify the number of job losses. Ars Technica reported that a source familiar with the situation said 9 percent of Access’ positions were to go, but that some workers could be moved within Alphabet. Access has about 1,500 employees, according to Bloomberg.

Barratt emphasized that five-year-old Google Fiber will live on in cities where it’s operating or under construction. The company is committed to remaining “a leader in delivering superfast internet,” he said.

“Our subscriber base and revenue are growing quickly, and we expect that growth to continue.”

The upheaval comes, he said, as the company focuses on “new technology and deployment methods.”

Those methods are widely believed to be connected to the company’s acquisition earlier this year of Webpass, a company that developed systems for wireless high-speed internet transmission.

A Federal Communications Commission filing released in August showed Google, in a top-secret project, had applied to test wireless internet delivery in Mountain View, Palo Alto, San Jose, San Bruno and San Francisco. Google wants to test the wireless broadband technology at up to 24 sites across the U.S., the filing said.

Some analysts have speculated that Google Fiber has been intended, in part, to spur Alphabet competitors to roll out ultra-high-speed service, to the benefit of Google, which can then run more ads past the eyeballs of more viewers.

“It’s not clear (Alphabet was) ever all that serious about doing this at any real size,” MoffettNathanson Research analyst Craig Moffett told the Mercury News in August.

Alphabet has run into trouble around the country, including here in Silicon Valley, in trying to get access to utility poles, to string fiber cable much more economically than by digging up streets.

For San Jose, the company had estimated that 60 percent of its cable would be underground and 40 percent aerial.

Google Fiber is operating in nine cities, none of them in California, and plans for Fiber in four additional cities, including Irvine, appear to be going ahead.

Google Fiber is also available in limited areas of San Francisco, Oakland, Berkeley and Emeryville, plus four other U.S. cities, via ethernet networks Alphabet acquired with Webpass.
