Hey there, Satish Sangwan
When looking at the documentation provided, it doesn't list physical addresses for Microsoft's data centres. This will most likely be due to security.
For audit and compliance requirements, Microsoft provides region‑level information and full SOC/ISO compliance documentation through the Microsoft Service Trust Portal: https://servicetrust.microsoft.com/viewpage/SOC
You will need to sign-in with your Microsoft account. This will allow you to access the locked files and save these files to your library for later use. For formal audit evidence, please refer to the SOC reports, ISO certifications, and Azure compliance documents available in the Service Trust Portal. The main portal is here: https://servicetrust.microsoft.com/
Hope this helps,
Nathan
