What must an administrator do to ensure a message is displayed during system downtime?

To ensure that a message is displayed during system downtime, enabling and customizing an information banner is the most effective solution. This feature allows administrators to create a visible notification that informs users of the downtime, its purpose, expected duration, or any other relevant information. By utilizing an information banner, administrators can communicate important updates directly to users accessing the portal, ensuring clarity and reducing confusion.

An information banner is typically designed to be noticeable, ensuring users are immediately aware of system status changes without requiring users to look for updates in less obvious places. This proactive approach fosters communication and transparency within the organization, which is crucial during periods where users may be interrupted in their workflows due to technical issues.

The other approaches do not directly address the need for displaying a message during downtime in a clear or effective manner. For instance, automatically configuring the system to generate messages may not guarantee that users will see the information at the pertinent times. Inviting users to view downtime notifications relies on users taking the initiative, which may lead to missed communications. Limiting access to the portal entirely would not provide any information and would instead hinder users from accessing necessary resources or support.
