AdSense Known Issues Page
The Inside AdSense blog today announced that they now have a Known Issues page. This page lists anything that Google is aware of that may cause problems, and possible work arounds.
I’m not sure if this is something that they have been working on for a while and it was just a coincidence that they launched this the day they had a major reporting outage, or if they whipped this together today. My guess is that it’s the former.
This will be a good place to check out if you notice something amiss with AdSense. I’m sure today’s outage caused a lot of publisher to panic (Are my sites down? Did I get banned?) and this should help next time something like this happens.
