No Ads shown on my sites. Just blank for 15 minutes.

Is there anyone experienced this?

This is the second time I saw no AdSense ads on my sites. No AdSense, no PSA, no replacement ads. Just blank. I tried to refresh the page but no luck. The AdSense preview tool shows ads. The first time is last night. I estimate to be 10 or 15 minutes long before the normal ads show again.

Yes i saw this yesterday for about 5 minutes, and today again for a few minutes. Maybe they are running out of adverts.

Maybe they are running out of adverts.

I don't think so. There must be something else.

Reasons:

1. No PSA's or Alternate ads shown.

2. All pages and industries were affected.
