The CEO of Google Access, which six years ago began installing broadband internet service Google Fiber in U.S. cities, said Tuesday he will be stepping down amid a halt in the network's expansion and upcoming layoffs.

In a blog post, Craig Barratt said the company has "refined" its plan to focus on new technology and delivery methods. Construction will continue in cities like Nashville, Salt Lake City, and Atlanta, where Google Fiber networks are current under way, as well as in upcoming cities like San Antonio and San Francisco. But plans will be put on hold in the 10 cities that have been in consideration for the high-speed internet system.

The announcement comes two months after the Wall Street Journal reported that parent company Alphabet was considering other methods of delivering high-speed internet after its first installations required more time and money than expected.

Barratt did not give any details on his next move, nor did he name his replacement. "I've decided this is the right juncture to step aside from my CEO role," he wrote. Barratt will remain on as an advisor to Alphabet CEO Larry Page.

The company is set to have a board meeting Wednesday, ahead of its earnings report on Thursday.
