I wanted to reach out to other Adsense publisher about the potential downfalls of CDN's especially CloudFlare.
About a month ago I noticed a sharp decrease in my CTR and CPC (nearly 300%!)
Concerned I began scanning my site and noticed numerous blank spaces and 95% of ads being displayed were irrelevant.

After numerous experiment I concluded that the culprit was CLOUDFLARE!
I turned off Rocket Loader/Minify on Cloudfare still was getting blank spaces/irrelevant ads.
I added mod_cloudflare in Apache and still was getting blank spaces/irrelevant ads.
I turned security settings to low and still was getting blank spaces/irrelevant ads.
After numerous failed attempts to correct the problem I decided to ditch Cloudflare and head back to my original Nameserver.

The next day my ads were displaying correctly & relevant to what I was searching.
Since the move back my CPC has nearly doubled & CTR is healthy.

I believe the problem is due to Cloudflare filtering visiter ip addresses.

Well that may or may not be the case with your account, but Adsense blank space ads happen across many sites on various hosting platforms so it's not indigenous only to Cloudfare or even CDN.
