Google has named its fiber unit GFiber, formally adopting the unofficial moniker it previously used to reference its Google Fiber business.

The rebrand was announced last week, as the company pushes on with its fiber merger with investment firm Stonepeak's Astound Broadband to create an independent fiber provider.

Google said that the rebrand won't change the services that the company offers, which include its 1-Gig, 3-Gig, and 8-Gig service offerings.

"We’ve been using GFiber as our primary name for over a year, and it’s time to make it official—Google Fiber is now GFiber. You’ll see it everywhere you see us," said Melani Griffith, chief growth officer, GFiber, in a blog post.

While the services are set to remain the same for now, it's not clear what will happen once GFiber's merger with Astound completes.

The new company will be majority-owned by Stonepeak, while GFiber's parent company Alphabet will retain a significant minority stake, though these shares weren't disclosed.

GFiber officially launched in 2010, but the service first went live in Kansas City in 2012. The firm is estimated to serve around four million customers.

The company operates in a number of states, including Alabama, Arizona, California, Florida, Georgia, Idaho, Iowa, Illinois, Kansas, Missouri, Nebraska, Nevada, North Carolina, Tennessee, Texas, Utah, and Washington.

Astound currently serves about a million customers across 11 states, while its fiber network passes more than four million premises.
