Case Study

Irish data center provider supports growing international demand for low-latency services.

With its ability to offer low-latency connectivity to both Europe and North America from a single hub, Cork Internet eXchange (CIX) is expanding into international markets. The company is also broadening its service portfolio by providing new services, including VPNs and an OpenStack cloud environment.

“Our customers want greater flexibility from their IT infrastructure and the cash flow benefits of buying IT as a service. As they depend on us more, we need our own infrastructure and network to deliver the highest levels of performance and reliability.”

Jerry Sweeney, Founder and Managing Director, CIX


Located in Cork, Ireland, CIX is a regional data center provider that offers colocation, managed services, and—more recently—cloud computing services. Its connection to North America via the new Hibernia Express subsea transatlantic cable allows CIX to deliver low-latency connections to European customers.

Business Challenge

CIX needed to meet increasing international demand for its low-latency data center services while managing an increasingly complex operational environment. CIX also is embracing open networking to complement the virtualized infrastructure being developed by its customers.

Business Solution

CIX uses EX4200 and EX4550 Ethernet Switches—deployed using Juniper’s Virtual Chassis technology—for 1GbE access connections and 10GbE cloud service connections respectively. The network edge features MX80 and MX480 3D Universal Edge Routers, SDN-ready routers that provide investment protection by scaling for bandwidth, subscribers, and services.

Business Results

CIX’s new network will enable continued business growth, while Virtual Chassis configurations and consistent implementation of the Junos® OS avoids operational complexity. Closely aligned to Juniper’s philosophy on open standards, CIX is committed to open networking and believes that Juniper gives it a competitive advantage over the rest of the market.

“Offering ever more sophisticated services to our customers is the key to our growth, and Juniper will be a key partner in delivering those services.”
