Pitronote Admin
“Maintenance Mode” is an add-on for Jira by Atlassian, created to allow Jira admins to set a maintenance landing page and redirect all users to it during maintenance time.
Jira admins can decide which users / groups can still use Jira during maintenance and not being redirect to the landing page.

By default, all Jira Administrators can access Jira when Maintenance Mode is active
