Go login to your Microsoft adCenter account and try to see if you can manage your search ad campaigns, the search ads that are displayed on Bing, Yahoo Search and their partners. Can you? Do you see anything? If not, you are not alone.

Starting this morning, adCenter advertisers have been complaining about the issue in the Microsoft Advertising Forum.

The first report came at 12 minutes after midnight. The advertiser said:

So the ads are still running but you cannot manage them, change them, pause them or delete them? I guess not.

Several other advertisers came in this morning to say they are having the same issue.

As of now, Microsoft has yet to reply to advertiser concerns, but I suspect the issue will be resolved as soon as they find out about it.
