Late last week, Google AdSense had an issue where publishers were unable to login to the site and manage their ads. The reports began coming in on April 10th and some earlier reports came in on the night of the 9th.
Both AdSensePro Jennifer and AdWordsPro replied to the issue on the 10th. AdSensePro Jennifer chimed in when it was fixed, saying "OK, things should be back to normal. You should be able to log into your accounts." AdWordsPro gave dialog during the downtime, saying:
Word has is that technical issues are now resolved, and that stats will catch up in the near future. I was told perhaps 4 or 6 hours, but am going to be on the safer side and tell you 6 to 8 hours.
I believe the issue was resolved some time Friday morning.
Now people are complaining about poor Easter day earnings.
