When you correct the links and save the document, the broken link checker will run again automatically.

Things the checker can check
You can run the broken link checker on any documents in Whitehall Publisher.
Right now it's not available on non-documents, eg People, Roles, or on file attachments. We plan to add this later.
Broken link reporting
We're improving the regular broken link report. We expect to run this fortnightly.
