How we know. Show HN and Product Hunt entries are judged by asking the domain whether it still answers: gone means it no longer resolves, refuses the connection, serves a parking page, or says plainly that it has shut down. An HTTP error is not counted as gone — a server that answers 404 is one somebody still pays for. Y Combinator entries use the status YC itself publishes, which is why only those can say acquired.
