GPU Colocation in Dublin
GPU colocation in Dublin sits within Ireland's hyperscale capital — a FLAP-D hub with ~1.2GW IT load and the densest cloud cross-connect ecosystem in the country (Equinix, Digital Realty, Echelon, Vantage, Maincubes). Best for EU data-residency AI workloads, multi-cloud anchored deployments, and 50–100kW+ liquid-cooled training. EirGrid moratorium affects new builds, not existing capacity.
Why is Dublin Ireland's hyperscale capital (and what are the caveats)?
Dublin is one of the four FLAP-D hubs (Frankfurt, London, Amsterdam, Paris, Dublin) that anchor European data-centre capacity. It is the European HQ region for Microsoft, Google, AWS, and Meta — and as a result, the city's IT load has expanded faster than the local grid was designed for. By 2022 EirGrid (the Irish transmission system operator) effectively introduced a moratorium on new data-centre grid connections in the Dublin region, with revisions and conditions added since. The headline implication: building a brand-new hyperscale campus in Dublin in 2026 is materially harder than it was in 2018.
For colocation buyers, this is more nuanced than the headlines suggest. The major operators — Equinix, Digital Realty, Echelon, Lumen, Vantage — secured power allocations under the previous regime and are operating against contracted reserves. As long as you're taking space in already-energised facilities rather than triggering new grid connections, Dublin is open for business.
Which operators offer GPU colocation in Dublin?
- Equinix DB1, DB2, DB3, DB4 — the densest interconnect ecosystem in Ireland. Cloud Exchange, INEX peering, direct cross-connects to AWS, Azure, GCP, Oracle.
- Digital Realty (incl. Interxion DUB1, DUB2, DUB3) — large-format colocation with interconnection-rich tenancy.
- Echelon Data Centres — purpose-built campus operator with high-density specifications and aggressive density commitments.
- Lumen Technologies — fibre-anchored colocation footprint.
- K2 Data Centres — Irish-headquartered operator with mid-density Dublin capacity.
- Vantage Data Centers (Profile Park) — large hyperscale-grade campus with liquid-cooling specifications.
- EngineNode / Servecentric / smaller regional — niche operators serving Irish commercial and SME tenants.
Why does Dublin remain attractive for AI workloads?
- EU data residency — post-Brexit, an Irish footprint is the cheapest way to maintain EU-based AI compute that is comfortably inside the GDPR jurisdiction without cross-border data transfer mechanics. Many UK and US AI companies use Dublin specifically for this reason.
- Cloud cross-connects — every major hyperscaler operates a Dublin region. For AI architectures that span owned colo and managed cloud (training in colo, serving in cloud, or vice versa), Dublin's cross-connect ecosystem is among the best in Europe.
- Talent and tax regime — Ireland's 12.5% corporate rate (now 15% for large multinationals under OECD Pillar 2) and English-speaking workforce make it a sensible HQ region for European AI build-out, even if the data centre is the smaller operational footprint.
- Connectivity — INEX (Internet Neutral Exchange Association) sits in Dublin, plus dense subsea cable adjacency to UK, North America (via Greenland route), and continental Europe.
- Climate — like Edinburgh, Dublin's mild climate supports lower mechanical cooling demand than Frankfurt or southern Europe, with PUE figures typically in the 1.20–1.40 range.
How does the EirGrid moratorium affect Dublin GPU colocation?
EirGrid's 2022 directive introduced strict criteria for new data-centre grid connection applications: minimum location requirements outside Dublin, grid-flexibility commitments (DSU/demand-response participation), and behind-the-meter renewable generation requirements at certain thresholds. Subsequent revisions have softened some of these conditions but not eliminated them.
Practical implications for an AI buyer in 2026:
- Taking space in existing energised facilities — broadly available, subject to operator-specific reserves. This is the path most buyers are on.
- Triggering new grid connection in Dublin metropolitan — extremely difficult in 2026, typically routed through 2028+ windows.
- New campus outside Dublin — operators are increasingly building in regional Ireland (Cork, Athlone, the broader Midlands) to access grid capacity.
- Demand-response and behind-the-meter renewables — large new tenants are now expected to commit to grid-flexibility programmes; smaller colocation buyers inherit the operator's compliance position.
What Dublin GPU colocation capacity is available right now?
Density: Dublin has the most credible 50–100kW per-rack capacity in Ireland, concentrated in newer Equinix, Digital Realty, Echelon, and Vantage builds. Older Dublin stock is 10–30kW with retrofit pathways.
Lead time: 8–16 weeks for sub-1MW deployments at operators with un-contracted reserves. Larger commits typically require operator-level conversations before dating becomes meaningful.
Cooling: liquid-ready commits are available across the major operators; direct-to-chip is increasingly standard at 50kW+ specifications.
What should you ask Dublin GPU colocation operators?
- Confirmed un-contracted reserves at the campus and the building
- Specific cross-connect costs to your target cloud regions
- EU data-residency posture — most are clean; a few have parent-company entanglements worth checking
- DSU/demand-response inheritance — what does your tenancy commit you to operationally?
- Carbon-matching commitment, particularly for buyers under EU CSRD reporting
