Mortality

Dead projects

Software this index carried, went back to, and could not find. Marked, kept, and counted — not deleted.

4,072 listings have been confirmed gone — 1.2% of the 334,545 the liveness check has reached so far. Each one was probed, found missing, left in place for 7 days, and probed again before it was marked. They keep their pages and stay in the catalog total; they leave the live rankings.

The date on each is when we confirmed it, not when it stopped working. We cannot know the second one. Confirmations now span 7 separate days, from 17 Aug 2026 to 8 Oct 2026.
