Business Internet & Enterprise Connectivity in Ireland

Dublin punches well above its size as a data centre city. Three-quarters of Northern Hemisphere subsea cables pass through Irish waters. The country has 14 submarine cables. AWS and Microsoft Azure have direct cloud on-ramps in Dublin. Equinix, Digital Realty, CyrusOne, Vantage, and Google all operate there. If you're putting compute in Western Europe, Dublin is often on the shortlist — and our connectivity into the city is built accordingly.

The Connectivity Landscape

Colt expanded its IQ Network in Dublin to connect over 350 enterprise buildings and 23 data centres, with a direct Dublin-London route. As Colt's number one global partner with a wholesale and Agent Partner relationship, we deliver via that network with the same pre-validated engineering and real-time SDN capability we apply across the rest of Europe.

Eir Business (Eircom) is the dominant Irish incumbent, offering NGN Internet with symmetrical speeds to 10Gbps. Vodafone Ireland provides SASE, cloud, and enterprise connectivity. BT Ireland sold its wholesale and enterprise business unit to Speed Fibre Group on September 1, 2025, and separately sold its Irish data centre business to Equinix — a significant market restructuring for Irish enterprise buyers with existing BT contracts.

INEX (Internet Neutral Exchange) is Ireland's primary internet exchange — not-for-profit, industry-owned, with PoPs across Equinix, Digital Realty, and Interxion Dublin. In 2025 INEX reached 1.3Tbps peak traffic and handled 2.3 exabytes. Dublin data centres offer 40–60 carriers and direct cloud on-ramps to AWS and Azure.

Coming infrastructure: Far North Fiber (Ireland-Alaska-Japan-Norway, 2026), Celtic Interconnector (Ireland-France, 2027–28), and Pisces (Ireland-France-Portugal-Spain). Ireland's already strong cable position is about to get stronger.

What We Deliver in Ireland

We've delivered internet connectivity services across 9 Chemist Warehouse stores in Ireland — a retail roll-out requiring consistent last-mile delivery across multiple locations. We also serve large capacity consumers in Ireland including mobile backhaul and insurance clients. Our Colt relationship gives us access to 350+ enterprise buildings in Dublin without relying on Eir's wholesale infrastructure.

For clients co-locating in Dublin's data centre cluster and connecting back to London, Frankfurt, or Amsterdam, we can manage that full circuit as a single engagement. Lead time: 35 working days via Colt on-net.

Frequently Asked Questions

What happened to BT Ireland?
BT sold its Irish wholesale and enterprise business to Speed Fibre Group (completed September 1, 2025) and sold its Irish data centres to Equinix. If you're a BT Ireland enterprise client, your contract has moved. Worth reviewing terms.

How long does delivery take in Dublin?
35 working days via Colt on-net. Off-net builds and regional locations outside Dublin take longer.

Which carriers do you work with in Ireland?
We don't work from a fixed panel. We qualify your requirement first — single circuit or dual, resilience model, lead time, vendor preferences — then recommend the right carriers for your specific address in Dublin. Colt, Eir Business and Vodafone Ireland are among the options in Ireland, but carrier selection is driven by your requirement and location.

Are there cloud on-ramps in Dublin?
Yes — direct on-ramps for AWS and Microsoft Azure operate in Dublin data centres as of January 2026.
