Zayo Group Holdings, Inc. announced continued investment and expansion of network infrastructure in the Seattle-Tacoma area of Washington. Driving demand for connectivity is both the region's position as a top-ranked tech talent market and its technology-focused industries including manufacturing, IT and clean technology. As part of the expansion, 400G wavelength capacity will be available between Seattle and Spokane by the end of June 2022, adding crucial IT bandwidth to a key route between two major Washington cities. Zayo is also rolling out a new product offer to new and existing customers in the greater Seattle-Tacoma area. The offer, called Shielded Internet Access, includes some of Zayo?s most popular services: Dedicated Internet Access, DDoS Protection and CloudLink, all within a single offer that will be competitively positioned against current market benchmarks.
