This morning I noticed that none of my websites are displaying the Google Ad blocks that are placed on the pages. My referral buttons and ad spaces are simply blank. I have them set to show community service ads in the event of a lack of available ads, but those are not showing up either. I am still able to log into my Google AdSense account, which does have earnings posted for today. In addition I have not received any email from Google about problems, etc. I strictly play by the rules. Is anyone else having a similar problem, or is this just me?
Update... I also went to some pages by otyher publishers and their ads are not showing up either. Is Google having ad downtime or something? Also note that the Google banner at the top of this page is missing. This is odd...
