(Telecompaper) US operator Windstream has agreed to sell its data centre business to TierPoint for USD 575 million in cash. Under the terms of the agreement, the two will also establish a strategic partnership which will enable them to sell their respective products and services to each other's prospective customers through referrals. The structure will allow Windstream to focus capital on its core telecom offerings while continuing to offer traditional data centre services to enterprise customers across a broader data centre footprint.
