About Zirrus

In 2022, the organization rebranded as Zirrus to reflect its transformation from a traditional telephone cooperative into a modern fiber broadband provider.
Zirrus has invested extensively in fiber-to-the-home infrastructure across its service territory in Ashe, Alleghany, Watauga, Avery, and surrounding counties. The company offers some of the fastest residential internet speeds in rural North Carolina with plans up to 6 Gbps.
