What does restoring access to a system involve after a fail-over?

Restoring access to a system after a fail-over primarily involves verifying system integrity before re-enabling access. This step is crucial because it ensures that the system is operational, secure, and functioning as intended before allowing users to log in or access the resources. Verifying system integrity can include checking for data corruption, confirming that all necessary services are running properly, and ensuring that there are no lingering issues from the fail-over event that could impact performance or security.

By prioritizing system integrity, organizations can prevent potential data loss, security breaches, or further downtime that could occur if users are granted access to a system that has not been fully verified. Once the integrity checks are complete and the system is confirmed to be stable and secure, access can then be restored to users in a controlled manner.
