Mortality

Dead projects

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

2,762 listings have been confirmed gone 1.4% of the 193,877 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. Today every confirmation carries the same date, because the check that issues them ran for the first time on 17 Aug 2026 and resolved the whole backlog at once. A death-rate over time will mean something after the next monthly pass; drawing one now would describe the day we started looking.
