Microsoft DUB07 is one of a pair of identical single-storey data centres, with DUB08, on Microsoft's second Grange Castle campus in Clondalkin, west Dublin. It sits between DUB06 to the east and DUB09 to the west.
Microsoft won permission for both buildings in February 2016. Each covers about 16,900 m² (181,900 sq ft). Construction was under way in October 2017, and both buildings were running by 2019.
Rooftop air handling units cool the data halls with outside air. Evaporative cooling supports them on the hottest days.
ESB Networks serves the campus from the Kilmahud 110 kV customer substation on site. EirGrid operates the transmission system. No behind-the-meter generation serves DUB07.
Fifteen standby generators back up the data halls, with a separate admin generator. Microsoft converted the campus generators from diesel to hydrotreated vegetable oil (HVO) in 2023 and 2024.
Microsoft runs twelve data centres at Grange Castle, from DUB03 (2009) to DUB15, plus the stand-alone DUB11.

Microsoft uses Containers (called ITPACs) to build out its data centers. These Containers are Shipping Containers fitted with all the necessary climate control, networking, server racks and other hardware necessary to be a “mini” data center all in one.
An Azure region is a set of data centers deployed within a latency-defined perimeter and connected through a dedicated regional low-latency network.
With more global regions than any other cloud provider, Azure gives customers the flexibility to deploy applications where they need to. Azure is generally available in 46 regions around the world, with plans announced for 8 additional regions.
An Azure geography is a discrete market, typically containing two or more regions, that preserves data residency and compliance boundaries.
Geographies allow customers with specific data-residency and compliance needs to keep their data and applications close. Geographies are fault-tolerant to withstand complete region failure through their connection to our dedicated high-capacity networking infrastructure.
Availability Zones are physically separate locations within an Azure region. Each Availability Zone is made up of one or more data centers equipped with independent power, cooling, and networking.
Availability Zones allow customers to run mission-critical applications with high availability and low-latency replication.
