For about 30 minutes or so I cant see google ads on my site or any other site, the ads on DP from google adsense is also gone. I am @ work so this might be coz they added a filter to prevent Adsense ads, but just wanted to confirm with others.
Since lifeplayer revived it a bit late, I'll add my two cents. I didn't experience any problems last night, but it depends if you're using firefox or IE, in IE some people just add the google syndication which adsense uses to restricted sites to avoid seeing the ads. In Firefox, many people use adblock plus which blocks adsense and other advertisements. Someone using your workplace or configuring it may have done the same.
I can see it,but did you know that internet explorer and fire fox web browsers can show different content media,scripts etc... so it might be your browser too
I guess it with the PC that you used, sometimes it happens to me also when I use PC in other places. Nothing to worry though.
