On Thursday, May 13th, 2010 the AdWords system will undergo maintenance from approximately 6:00PM to 6:30PM PDT. While you may not be able to sign in to your accounts during this time, your campaigns will continue to run as usual.

While, AdWords system maintenance typically occurs on the second Saturday of each month, this update was delayed due to the Mother's Day holiday in the U.S. last weekend.

We'll continue to update you via the blog as we always have, but please make note of the May 13th date and of our scheduled maintenance further down the road.
