Oracle Cloud Infrastructure (OCI) had data centers in multiple regions around the globe. These regions are geographical locations where Oracle Cloud Infrastructure services are hosted. Each region is a localized geographic area and typically contains multiple availability domains.

Here are some of the regions where Oracle Cloud Infrastructure had data centers:

North America

• Ashburn, Virginia, USA
• Phoenix, Arizona, USA
• Toronto, Canada

Europe

• Frankfurt, Germany
• London, UK
• Zurich, Switzerland

Asia-Pacific

• Mumbai, India
• Sydney, Australia
• Tokyo, Japan

Other Regions

Please note that Oracle continues to expand its global footprint, and new regions and availability domains may have been added after my last update. For the most current information, it’s best to consult Oracle’s official documentation or support channels.
