ZAYO EXPANDS FIBER NETWORK IN OHIO.

Zayo Group Holdings, Inc. is expanding its fiber infrastructure in Ohio, making significant investments in metro network to support enterprise and mobile carrier customers driven by an anchor customer deal. The network expansion will further strengthen Zayo's dense Ohio metro networks and add nearly 300 new route miles in the Youngstown and Akron area.

Zayo's existing network provides long haul connectivity throughout the state, including the Cleveland/Akron/Pittsburgh corridor. This build will also enable additional diverse options through Youngstown.

The expansion illustrates a trend toward densification of Tier 2 and 3 markets and diverse connectivity between them. The growth of bandwidth intensive content, OTT streaming services, and IoT applications is leading companies to deploy services at the edge of the network. Further densification will be required for 5G.

The expanded network will provide healthcare, universities, local government, data centers and enterprises in Youngstown and Akron with wavelength and other fiber-based solutions along the route. Construction on the project will start this quarter and is anticipated to be completed in 2020.
