Just a quick heads up that the Google team has posted a notification at Google Groups that the AdWords team will be conducting maintenance this Saturday.
Both the AdWords login console and the API will be offline between 10am and 2pm pacific time. Here is the message from Jeffrey Posnick, AdWords API Team:
We'll be performing routine system maintenance on Saturday, January 10 from approximately 10:00am to 2:00pm PST. You won't be able to access AdWords or the API during this time frame, but your ads will continue to run as normal.
