The service stores and constantly checks pages with 301 and 404, which were in the sitemap, but were deleted after checking or as outdated.
Need to be able to indicate that this type of page no longer needs monitoring and can be removed from existing monitoring, no longer monitored.
In the case, of course, if such a page appears again in the sitemap, then the error message about such a page should appear again, if it still has a 404 or 301 status.
