i was very afraid when i logged in adsense and see that my earnings are only 1/10 what it used to be.. now i can comfort myself by thinking it is because the maintenance.. cant I??
Adense.google.com opens but loads real slow for me and I have only 25% of typical income for a Sunday morning.
That time google adsense make maintain. Who is use google adwords they know the maintain time Google publish their maintain time on google adwords users page. Every month its happen So don't worry about it.
