News post not showing up in feed

Have any of you seen random behavior where occasionally a new News Post doesn't show up in the News web part for a period of time? I'm assuming it's some sort of caching or CDN issue, but I will say that clearing cache doesn't resolve it. If and when the issue occurs, it appears to take about an hour or two before the article starts showing up in the feed, as expected. If anyone has seen this, do you have any workarounds or ways to kick start it, besides organizing that article to the top of the feed manually?
