On Saturday, September 12th, 2009 the AdWords system will be unavailable from approximately 10AM to 2PM PDT, for maintenance. While you won't be able to sign in to your accounts during this time, your campaigns will continue to run as usual.

AdWords system maintenance typically occurs on the second Saturday of each month from 10AM to 2PM.

We'll continue to update you via the blog as we always have, but please make note of the September 12th date and of our scheduled maintenance further down the road.
