Is the server having issues counting upvotes/downvotes?

I'm noticing that the upvote/downvote counter on various posts is a bit erratic. I saw it in realtime going to 1.1K up to 2 up and 13 down to 8 up.

I made a post a little bit ago and the instant I posted it it had 8 upvotes on the total counter. Hovering over it revealed it had only 1 upvote.
