Microsoft datacenters play a crucial role in our everyday lives. They operate around the clock to support a wide spectrum of critical services, from the life-saving work of doctors and first responders to essential needs such as online banking and remote work. Datacenters also quietly power everyday necessities such as online education, video calls with family and deliveries to your doorstep. Our global network of highly secure datacenters spans 34 countries, connected by over 165,000 miles of fiber optic cables. They are the backbone of Microsoft’s Azure cloud platform and enable everything from AI infrastructure and collaboration tools to entertainment.
