Just incase you discover you are unable to login to your account on Friday evening, don’t worry, we will all be seeing the same thing. It seems the engineers on the AdSense Team are taking advantage of the slower time to do some maintenance.
While many of you may be on vacation this week, some of our engineers are working hard to ensure the performance and stability of AdSense. Occasionally this means taking down the main AdSense site (http://www.google.com/adsense) for updates. At 8PM PST this Friday (12/30), it will be unavailable for up to 6 hours while we complete some engineering work. Of course, all your AdSense ads will still serve properly and all your stats and earnings will be recorded as usual. We’ll bring the site back up as soon as we can.
I wonder if there will be something nice and shiny for us to play with when the maintenance is complete 😉
