When using maintenance mode, what remains enabled?

When a cloud service or application enters maintenance mode, it generally allows for specific functionalities to remain operational while restricting other activities to safeguard the environment during updates or repairs. Alerts remain enabled during maintenance mode to ensure that any critical issues or events are still reported to the system administrators or relevant personnel. This capability is crucial because it allows the operations team to be aware of any problems that might arise during the maintenance process, enabling them to take necessary actions quickly.

Maintaining alerts is important for monitoring the health of the system, so administrators can respond promptly to any incidents that occur, even if user functionalities are limited. This proactive monitoring helps ensure that while the system is being serviced, it does not worsen or lead to further complications that could impact the availability or reliability of the services provided.

Other functionalities like customer access, logging, or the ability to power on virtual machines may be restricted in maintenance mode to prevent conflicts or further issues while updates are being applied, but alerts are maintained to support continuous oversight.
