Adsense Ads Not Connected?

[Ricardo]

I'm very new to Adsense, but I noticed for a while yesterday that my Adsense ads weren't displaying the ads, but showing a message I see when the page is unavailable. At this time, the site took a long time to load, too.

Does anyone know what might have caused that?

I started getting this on some of my pages too.

you should bare in mind tho when you make a new ad unit it takes a little while for it to be created and come online.
