What happens to protection during a DSA upgrade?

During a DSA upgrade, no protection is lost, but it typically requires a restart. This is because the upgrade process usually involves the application of necessary updates and changes to the system that enhance functionality and security. Although these modifications require a restart, the design of the upgrade process ensures that the existing protections remain active until the restart occurs. This is important for maintaining security integrity and minimizing potential vulnerabilities during the transition phase.

It's worth noting that while some actions may temporarily affect service availability, robust systems are designed to minimize any risks associated with upgrades, allowing for uninterrupted protection during most of the upgrade process.
