Google in the past two years put in place plans to expand its Fiber fast internet service to more than 20 cities. Inside the company, executives harbored bigger ambitions: to deliver service nationwide and upend the traditional broadband industry.

Google parent Alphabet Inc. reset the project on a more humble footing on Tuesday. Craig Barratt, head of the Access unit that includes Google Fiber, is leaving, and about 9% of staff is being let go, according to a person familiar with the situation. The business has about 1,500 employees, meaning there will be more than 130 job losses, Bloomberg reported.
