Ask HN: I have 600 karma but can't see downvotes

[longnguyen]

Basically the title. I used to see the downvote button when I reached 501 karma but now I don’t see it/can’t downvote.

Is something changed recently that I’m not aware of?

Thanks

You can't downvote articles, you can't downvote replies to your own comments, you can't downvote comments that are a day or so old and older, etc. So make sure you're looking at a thing that's actually downvotable (e.g. a toplevel comment in a front page thread).

Ah you’re right. Thank you.

Never mind. Suddenly I can see downvote button now so maybe just HN server hiccup?

From time to time (like once or twice per month) HN goes to read only mode for a few minutes (while dang is making some weird update?), and the downvote buttons disappear. Can this be the explanation???
