FAQ
Which is the largest data center company in Ireland?
By tracked facilities: Digital Realty (Interxion) with 9 sites. By published capacity: Pure Data Centres Group with 54 MW. Facility counts and MW come from operator pages and registries; published megawatts describe site design, not vacant capacity for a new order.
Do all of these companies sell colocation in Ireland?
No. The list includes colocation and wholesale operators as well as hyperscaler- or enterprise-owned sites that do not sell space. Open each facility card for status, certifications and the operator's own page before requesting a quote.
How is this list of Ireland data center companies built?
From the Coloprice catalog: every facility is recorded from a primary source (operator website, press release, certification registry), so a company appears here when at least one of its Ireland sites is tracked. No operator pays for placement, and the ranking is not for sale.
