Why this happens
Informational — not a failure. Visitors see This site is temporarily under maintenance. Please check back soon (or custom copy). You remain signed in as privileged staff.
Diagnose and fix
1. Finish maintenance work; turn off full-site maintenance when ready.
2. Customize visitor copy under Maintenance page content.
3. Optional Maintenance countdown.
4. Use upload/download-only maintenance if you only need partial downtime.
