It is not uncommon to see posts in the forums about the Google AdSense reporting being slow or even being "stuck," stop reporting. But normally it doesn't last this long and the reports are not this widespread.
Again, I am sure the reports will be back to normal soon, if not already.
The first reports came in early yesterday evening, a little before 6pm EDT. There are some people saying the reports look fine this morning whereas some are still saying there is a delay or complete stoppage of the reporting.
Are the reports delayed for you also? Do you freak out or just decide to wait it out?
