Recently I was serial down-voted by a unhappy fellow SO user when I marked their question as off-topic. Naturally, I waited for 24-hours and the serial down-vote was indeed reversed. However, I noticed that my vote counts for all my questions did not update (See Fig A). Curious, I clicked into each question and clicked on the vote counts and, like magic, when the vote breakdown appeared, the vote was "updated" to the pre-downvoted state. Refreshing my user profile on SO also shows the updated vote count for that question only.

I recognized that the "outdated" vote count plagues all the votes that were reversed and that refreshing the page, logging out and in again both did not solve the issue.

Voting overview in User Profile

The highlighted red box will not show updated votes for every question/answer that had its voting reversed.

Question with outdated vote

The actual Q&A page will also show outdated votes until I press View upvote and downvote totals in which the "updated" vote is displayed and updated everywhere else (Both Fig A and Fig B).

Unless I'm missing some great detail here, can someone explain to me why this is? (And also, can anyone else confirm this behavior?)

  • @RichardTingle On my end (i.e my computer) or the server's end? – initramfs Nov 11 '13 at 16:24
  • Server end, a lot of things on stack exchange are heavily cached to enable it to sustain the load its under – Richard Tingle Nov 11 '13 at 16:25
  • @RichardTingle Sorry if it sounds stupid but, is there any "solution" to this? Afterall, I did come on SO 5 ~ 6 hours after the vote reversal was made... Do they really cache data for that long? – initramfs Nov 11 '13 at 16:27
  • @CPUTerminator Definitely. Things like these may be cached for days. Or cached until updated.. ie, someone checks-vote-count/upvotes/downvotes it, forcing it to update. – Josh Crozier Nov 11 '13 at 16:28
  • We'd need a dev to answer authoratitively (one will probably be along shortly) but yes. The solution is basically to wait for the caches to update – Richard Tingle Nov 11 '13 at 16:29
  • @RichardTingle Oh what fun... I already manually "Check vote counts" everything that was down-voted, can't stand those -1s. Thanks for the information :) – initramfs Nov 11 '13 at 16:30
  • This question is related. It seems like the same issue. I have seen these invalidated votes go for quite some time without ever being updated, until I clicked to expand the votes. – Andrew Barber Nov 11 '13 at 17:02
