Ad Serving Issues

[jbayabas]

I seem to be having ad serving issues with some of my ad codes in different browsers. My ad sizes 300x250 and 728 are not appearing in Safari, only the backup ads will show. Once I replace them with responsive or 336x300, they will suddenly appear. Very strange. It appears that I am losing money because of this glitch. WTF is going on! Something is really broken with Adsense!

I've been seeing blank ad spaces off and on in Chrome for months. All sizes but none are responsive.

The only way I can explain my revenues over the past number of days is this issue. No other possibility in my mind. There is bad, then worse, then worse than worse, then there is this. That's about where I'm at on this. What I don't understand is how there is next to no communication or discussion. Very puzzling. I can say that one site I have, which gets about 1/10th the traffic, is almost performing as well. One site is almost beating 10 sites combined. I may be understating that. I guess it's time to check in the actual Google forum. I thought this would be the place for info, but I guess not.

Noticed slow ad load times in yesterday. So, I guess, it's not just me.

I put in html pages as backfill on my ad units and was stunned at how often the html gets hit (I put a Google Analytics tag on it so I could track it) Today I'm packaging up all the stats and sending them to AdSense.

@netmeg, what percent of the traffic hits the tag? Also, is there a big difference between desktop and mobile?

@Netmeg. How's your backfill? Are they still high? Im still having ad serving issues and my backfill ads keep running instead of adsense.
