Weird "advisory", non ad info inside google ads frame

Just an interesting thing I saw. I was just doing a weekly check of my network when I saw this weird output in an adsense ad. It's like an advisory. I checked the source of the iframe and it was a js document.write, definitely from google - a reload made it go away.
Anyone else seen this?
