It will be developed in three phases, with the first phase slated to open by mid-2022 and offer roughly 2,900 square meters of space. At full build out, the facility is expected to offer more than 11,000 square meters of total equipped space and 24 megawatts of customer capacity.The expansion of the Zurich campus is a strategic fit as the city has emerged as a potential digital hub.

CONE and CoreSite Realty Corporation COR, are likely to continue witnessing substantial demand.However, a competitive data-center landscape is a concern for the company.
