Summary
Repositories suddenly missing from the Linked repositories page ($BAMBOO_BASE_URL/admin/configureLinkedRepositories!doDefault.action) inside Bamboo even though they still exist inside the database. The Linked repositories page shows up empty with a "No repository configured" message.
Diagnosis
If the list of repositories inside the Linked repositories page is empty look for the presence of NullPointerException in the <Bamboo server home directory>/logs/atlassian-bamboo.log files, such as the following:

The repository cache used by Bamboo to display the list of repositories inside the Linked Repositories page might be corrupted causing the NullPointerException as well as the missing repositories/ empty page.
Solution
The solution, in this case, would be to restart Bamboo. A restart of the application will flush the repository cache. This should be enough to bring the repositories back inside the Linked Repositories page.
