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.

In the meantime, we hope you have a happy and high-earning new year!

Season's greetings!
