selected pages go "dead" to adsense

PSA's only on certain URLs

[amznVibe]

I just noticed a very few of one site's pages have gone to PSA's only.
All the rest are running just fine. No word from Google.

Ad sandbox suggestions for the pages returns nothing.
If I change the url, even slightly (adding or removing www.) ads show fine.
These are very ordinary pages, has the mediabot gone goofy?

Hmmm.. Happened to me 2 days back and still continuing.

Some pages are showing PSAs where there is no reason I can think of, or showing site's default ads which are totally irrelevant to page content.

On the other hand, mediabot has been visiting several pages, but not these.

Usually I get mor or less relevant ads instantly or max within 24 hours. This is strange for me.

We had a page that kept doing that for no apparent reason. Finally it straighted itself out. It took a few weeks though.

I have a theory that mediabot sometimes stalls when reading in a page (or it's the server's fault) and it sets the "no valid content" flag, until one day it decides to visit again (perhaps after "x" number of visitors cause the adsense frame to load).

I sure hope it doesn't take weeks to fix itself.
I've routed the page to a new url but it shouldn't be there permanently.

I added 4 brand new pages Saturday all in the same specific topic on a very general domain. One came up showing perfect ads on the first try. The other 3 started out showing the same ads as the domain home page. Played around with content a bit and now they all show PSAs! Can't get them to go back to even generic ads.
