Clarification: I collected HTTP response codes from top 10,000 "Show HN" projects published since 2006. Half of them returned 200. The others returned timeouts and redirects, which indicates that they perhaps get closed.

So, what's happened to them? It's interesting to hear your Show HN project's story.

And, yes, supporting links:
