Some thumbs aren't showing, but if you click on them, you get the full sized pic. That means this page isn't loading correctly, but the media servers from the new IPs are working.
The problem is in this page, not the image servers. I'm not sure, not a professional developer, but it looks like the js isn't functioning correctly to call the image from the external server. See this:
The external media server isn't creating thumbs, so when this current page calls for thumbs, nothing is loaded. Only when the current page calls for full-sized images does it work.
