Our Approach

Data Centre Colocation is the physical foundation and starting point for digital strategies. For over 20 years, BT Ireland has been providing secure colocation services in our own data centres, where our strength is recognising that every customer is unique. World-class facilities in Dublin and Belfast are built to Tier III specifications and managed to ISO and ITIL standards by engineers and service teams with the highest professional certifications.
