Administrators may need to verify if links inside their Confluence pages are working properly. Doing that for a huge space requires time, since there's no automated way of doing this. In a space with 1000 pages, an administrator will need to check page by page and validate all links manually, which is extremely time consuming.
Confluence should have an automated way of verifying all links inside a given space and return a report for administrators to fix broken references.
There's a Knowledge Base that seeks to help administrators who need to run through this task.
