Yes, I am seeing them on all my sites too. I came here to see if others have the same problem.

ads are showing for me.

They seem to be back now. I think it was showing psa for a short while.

I saw it and almost fainted until I checked other sites. The ads are back on now.

Yeah ads are back! Phew. Short n sweet

I had them too.

I immediately went to sign in hoping and grimacing that I didn't have a Google "Dear John (Buz) Letter" waiting for me.

Glad to see others had the same thing.

We experienced a very brief (under 5 minutes) issue that caused Public Service Announcements (PSAs) to appear on publisher pages for a few minutes this afternoon. Our engineers diagnosed and resolved the issue immediately, and your ads should now be back to normal. Thanks for reporting this, and we appreciate your patience.

Come on...tell us what caused this, it's interesting:-)

We noticed this blip, and it doesn't seem to of gone away...! The site is content rich and shouldn't suffer from no relevant advertisers, it has a valid privacy policy, yet on most (not all) pages there is nothing but the grey PSAs!

Is anyone else seeing an ongoing problem?

I just looked at one of my sites, and I am having the "no adverts at all" problem still.

Had to go to a site that wasn't mine that has adsense on it, then went back to mine, and they've appeared again.
