Microsoft expands US Azure regions and Availability Zones

Microsoft has announced major expansions of its Azure cloud and AI datacenter infrastructure across the United States, including a new East US 3 region in Atlanta and new Availability Zones in multiple existing regions.

• Infrastructure expansion: Microsoft will launch the East US 3 Azure region in the Greater Atlanta Metro area in early 2027, designed for advanced Azure and AI workloads, with Availability Zones for resiliency and facilities targeting LEED Gold certification and alignment with Microsoft’s carbon, water, waste, and sustainability commitments; additional AZs will be added in North Central US (by end of 2026), West Central US (early 2027), US Gov Arizona (early 2026), and expanded in East US 2 (Virginia) and South Central US (Texas) in 2026.
• Government and customer focus: Microsoft will add three Availability Zones to the US Government Arizona region in early 2026 to support zone-redundant, compliant architectures for government and Defense Industrial Base customers, complementing the Azure for US Government Secret region launched earlier in the year; customer examples include the University of Miami using Azure AZs for disaster recovery in a hurricane-prone region and the State of Alaska consolidating infrastructure and improving resiliency by migrating to Azure.
