As many know, there is little support available directly from Google when AdSense ads just happen to disappear. This happened to me this morning (and they're still gone), and I have been trying to troubleshoot the problem.

I found something interesting, and I'm not sure what it means. In the "Reports" section of my AdSense account, I clicked on the Site Diagnostics tab. Inside, there is a listing of 2 URLs that have been blocked (one on Aug 31, the other on Sept 1 (yesterday) - at least, those were the last crawl attempts. But what's interesting is that both URLs are NOT on my server. One of those sites put my site in an IFrame, and the other one, I couldn't get into because it was password-protected (google got in, however..)

Is this typical? I thought Site Diagnostics only referred to my site... could these two sites be the reason my site is not being served ads today? Or is AdSense just having technical difficulties today..
