One of the unique features of Oh Dear is that we crawl your entire site and report any broken links. Our broken links report had two main categories: In both categories, the problem is caused by something related to the site's content. In most cases, a page you're linking to was removed or archived. The solution is often letting the content manager of the site fix this. Today, we're introducing a third category in our report: internal broken links that resulted in a 5xx status code.
