The following question was asked 19 hours ago (as of when the meta question was asked), but isn't appearing in the "Newest questions" for java from that time period.
Here's the question, showing that it was asked 19 hours ago
Here's the "Newest question" feed for java for the corresponding period. It contains questions asked 18 to 20 hours ago, but not mine. The URL for this screenshot was https://stackoverflow.com/questions/tagged/java?page=10&sort=newest&pagesize=50
My question hasn't been downvoted into oblivion, or closed, and I don't have Stack Overflow configured to hide questions in my ignored list.
The question is only on page 10. If I have 50 questions per page, does page 10 turn into my page
Currently, it only has 10 views. I don't know whether that's because it never appeared on the java newest question feed, or was a boring question.
