Original post - see below for the edited version:

I've recently noticed that some questions for which links were added in comments did not appear in the list on the right.

Is this a bug or was the behavior of the list of linked questions changed intentionally? Or is there some delay before the linked question appears? (I did not notice any such delay in the past. IIRC after adding a link in an answer or a comment, after refreshing the page, the link was already in the list of linked questions.)

I did not find anything in recently asked questions tagged linked-question at meta.SO. The tag-wiki still says that the linked questions come from questions that users have linked in the question, their answers, or in comments.

Some examples:

If I stumble upon more examples, I'll add them here.

EDIT: When I've checked the question now (2 hours after the comment was added), the question is in the list. So now my question is basically why is there the delay between adding a comment and adding link to a list. (I wonder whether someone can confirm that this used to be immediate.)

  • $\begingroup$ It is now shown in the list. If anything I expect there to be a small delay. Just like badge awarding and such. $\endgroup$ Nov 8, 2012 at 8:55
  • $\begingroup$ @Willie Thanks for the reply. I've just noticed this too and edited my question accordingly. IIRC this used to be almost immediate, so it surprised me. $\endgroup$ Nov 8, 2012 at 8:57
  • $\begingroup$ Now in a different question the links appeared within 5 minutes (which is quite good compared with the question I mentioned in the post, where after 40 minutes the links were still missing). $\endgroup$ Nov 8, 2012 at 10:49

    $\begingroup$ until an official answer is available, just pretend that the internet tubes were clogged for a while, then the plumber came along... $\endgroup$ Nov 8, 2012 at 11:00
  • $\begingroup$ Today everything works again in the way as it used to. I've posted some comments containing links here at meta. Right after posting the comments I refreshed the page and the questions were already in the list of related questions. $\endgroup$ Nov 15, 2012 at 6:28
