Was404.fyi's field guide to dead links
A practical guide to determining whether a broken page is truly gone, temporarily unreachable, or merely moved.
Field notes
The guide separates a missing page from a missing site, treating each as a different kind of web disappearance. Its troubleshooting sequence includes cache-bypassed reloads, bare-domain checks, navigation inspection, Internet Archive snapshots, and quoted-phrase searches. The same page introduces DomainRiff, which states that it can generate three possible futures for an owned domain, along with a prompt, logo directions, and a colour palette; that workflow sits behind Google or GitHub sign-in.
