Dead link checker

We ask each site for the page without downloading it, follow up to four redirects, and record the final status. For every broken link we look up the closest copy in the Internet Archive's Wayback Machine.

Any 4xx or 5xx answer, a timeout after 8 seconds, or a domain that no longer resolves. Some sites turn away automated checks with 403 or 429, so open those in a browser before you delete them.

Up to 50 links per check, and a few checks a minute. Private and local network addresses are never contacted. Your list isn't stored.
