Microsoft adCenter postponed their maintenance work in June. But this month the work will be done. The upcoming maintenance is scheduled to take place on Saturday, July 14. This announcement was made by the adCenterEU on WebmasterWorld, DigitalPoint Forums, and Search Engine Watch Forums.
Due to the maintenance procedure, Microsoft adCenter will not be accessible for 14 hours starting from 10:00 A.M. Pacific Time (18:00 P.M. GMT). During this period, the current keywords of clients and ads will work normally; but no one will be able to access adCenter. Even after the scheduled maintenance, there may be some delay in reporting for up to 24 hours. The adCenterEU has advised their clients to make the required changes in their account beforehand.
