Question for Neil about RS 3.0

For the last few days, the comment section and member diaries are “getting stuck”. I can post, see my post in the thread and even see them when looking in my diary. But when I refresh the front page, these two sections don’t update, until maybe an hour later?

I’m sure you probably know about it, but I figured I should mention it. I am curious why it is happening though, seems to be a very recent change.
