We've identified the root cause, taken a corrective action, and are continuing to monitor the publishing queue as it catches up. Change publishing should be returning to normal soon.

Our publishing queue, which takes changes from the UI & API and pushes them to the ad servers, is currently backed up and taking longer than normal to process your changes. Most folks are seeing only a slight slowdown of a few minutes, but our heavy API users will see a considerably longer slowdown. We are investigating now.
Ad serving is NOT affected. All ad serving is working normally.
