Adsense Outage Today

From the Adsense forum on webmasterworld, posted by AdsenseAdvisor (a Google employee):

"Hi folks,

Yesterday we had some technical difficulties with our ad servers, which was the reason for the public service ads many of you saw on your pages. However, the problem's been resolved and the ads should be back to normal.

As usual, if you're still experiencing problems with your ads, shoot an email to the AdSense team. They're standing by, ready to be of assistance. :)

ASA"
