Google Fiber, now known as gFiber, has reached an agreement to take over Ting Fiber's dark fiber network lease in Colorado Springs.

Ting Fiber's parent company, Tucows Inc., announced that its subsidiary had agreed to transfer the lease, though it didn't name gFiber.

An SEC filing revealed that gFiber will take over the lease and will be substituted for Ting as the tenant.

Under the agreement, Ting leases dark fiber and colocation space on CSU’s municipal fiber network in Colorado Springs, Colorado, and serves as an anchor Internet service provider on that network.

Financial terms of the deal were not disclosed, though the transfer is expected to close on March 31, 2027, subject to customary closing conditions.

Tucows said that its related parent guaranty is expected to terminate by the end of April 2027, following closing and satisfaction of certain post-closing obligations.

The company added that Ting will continue to serve its Colorado Springs customers through the transition, which will be completed no later than June 30, 2027.

It will mark an exit from Colorado Springs for Ting, which also operates in California, Idaho, Maryland, North Carolina, Virginia, and Arizona.

"Our priority throughout this process is our Colorado Springs customers, and Ting will continue to provide the same service and support through the transition," said Dave Woroch, president and CEO of Tucows. "The move also aligns with Tucows' ongoing strategic process for Ting."

Google's fiber push

In a separate announcement, gFiber said that Colorado Springs City Council approved its lease agreement with Colorado Springs Utilities to use their new utilities fiber optic network to connect local residents to gFiber’s Internet service.

"This builds on our growth in Colorado, expanding our service beyond the Denver metro area. As a tenant on Colorado Springs Utilities’ network, we’ll be able to connect local homes and businesses even more quickly and with less neighborhood disruption," said Louis Lipner, head of strategic partnerships, gFiber.

The company was previously rebranded to GFiber from Google Fiber earlier this year, though it appears to have undergone another rebrand in recent weeks.

The previous rebrand came shortly after Google announced it will combine its fiber unit with investment firm Stonepeak's Astound Broadband to create an independent fiber provider.

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
