Why are cloud providers generally unwilling to grant physical access to their data centers?

Cloud providers are generally unwilling to grant physical access to their data centers primarily to maintain security by keeping the physical layout confidential. By restricting access, cloud providers can better protect their infrastructure from potential threats, such as unauthorized access, tampering, or sabotage. The physical security of a data center is critical; it includes the arrangement of servers, network equipment, and security measures that could be compromised if individuals were allowed unrestricted access. Keeping the layout and details of physical security measures confidential is a strategic approach to fortify defenses against both internal and external threats.

Additionally, other factors contribute to this practice, such as the importance of controlling who enters the data center to prevent breaches and ensure that only trusted personnel can interact with sensitive infrastructure. However, the primary reason is rooted in the need for heightened security and confidentiality regarding their physical assets and the measures in place to protect them.
