Zayo invests $90M to enhance its Tennessee fiber network

March 20, 2025
The updated network backbone is designed to fuel innovation, education and economic expansion.

Zayo is putting down $90 million to expand its fiber network across Tennessee, connecting the state’s primary data centers and educational institutions.

The initiative targets advanced network infrastructure to power hyperscale and data center campuses, supporting the rapid expansion of the region's artificial intelligence (AI) and other high-bandwidth workloads.

While this is Zayo’s latest expansion effort, it’s not the only one. In 2020, Zayo added 50% more fiber to its Tennessee network footprint around Nashville, Memphis, and Knoxville.

“This investment will expand our network’s reach, strengthen connectivity for K-12 education, and support the infrastructure needed for Tennessee’s growing digital economy,” said Michael McKerley, SVP of Zayo Managed Services.

Focus on education services

Another key focus of the new network investment is to bolster its services to the state’s education system.

Today, Zayo provides network services to schools in 139 of Tennessee’s 147 districts.

Through its acquisition of Education Networks of America (ENA) in 2021, Zayo became the largest independent provider of K-12 E-rate services, connecting almost 20,000 schools in the U.S.

For almost 30 years, Zayo Education has delivered mission-critical connectivity across urban and rural communities and remains the state’s top E-Rate services provider.

Zayo currently connects 94% of Tennessee school districts with managed internet and wide-area networking (WAN) services, ensuring K-12 students have secure access to digital learning, regardless of location. With this investment, Zayo is expanding its reach to underserved communities and reaffirming its dedication to bridging the digital divide in Tennessee.

Scaling infrastructure

Zayo’s new Tennessee network investment is the latest in new infrastructure expansion efforts.

In January, it unveiled a project to add over 5,000 new fiber route miles to support growing AI workloads.

Earlier this month, the company announced it is acquiring Crown Castle’s fiber solutions business.

By acquiring Crown Castle’s fiber business, Zayo will enhance its profile in the wavelength services market, where it has competed with Crown Castle and Tier 1 incumbent players like AT&T, Lumen, and Verizon.
