To all AdSense publishers, if you noticed that your AdSense earning today is much lower than usual, don’t panic! Your AdSense account should be fine, but Google has problem to update the AdSense stats up to time.
In fact, the AdSense update delay is affecting all the stats: impressions, clicks and earnings. Again, don’t panic!
On the other hand, AdWords stats also frozen and confirmed by Google AdWords.
Yes - some advertisers are seeing a delay in their stats today. The engineering teams are aware of this and, as you might imagine, are working to resolve it as a priority.
Please know that ads have continued to run as normal. This issue revolves around the reporting of statistics only, and does not impact ad delivery.
While there is no official announcement on AdSense blog, there is an official response on Google Groups:
Hi everyone,
I’ve escalated your reports to our engineers, and they’re currently investigating the issue. I’ll be sure to update this thread as soon as I have any more info — thanks for your patience in the meantime.
