A one-page site with a black hole that you feed with files.
The name follows the catalogue format real holes use (TON 618, Sgr A\*, M87\*). TON is the actual Tonantzintla quasar catalogue; 404 is the thing that is no longer there.
The old address blackhole.mironovjm.workers.dev still works so that links already handed out keep resolving. The canonical one is in .
Drop a file and the hole gets heavier. 18.5 GB = one Sun. One declared fiction (1 byte = 10²⁰ kg); everything else is real physics computed from that mass.
