Microsoft adCenter will be unavailable during an upgrade starting this Friday September 7th, beginning at 6:00 P.M. Pacific Time (2:00 A.M. GMT Saturday 8th September), and continuing for up to 8 hours.
During this time, your current keywords and ads will continue to run normally; however, you will not be able to access adCenter. Please make any needed changes to your account beforehand if possible.
After the scheduled maintenance, reporting will be delayed for up to 72 hours. On the adCenter Reporting tab please check the timestamp at the bottom of the page to see when the data was last updated.
