Posters at the DigitalPoint forum spotted a major glitch in the MSN adCenter. I contacted my reps and they were well aware of the situation.
I was told they will not be charging the accounts these overbidded amounts. Obviously - but I was impressed with the response time and knowledge of the situation.
MSN had this info to share:
A number of customers have very high Average CPC and spend amounts in adCenter over the last 24 hours which are much above their bid amounts for keywords. This seems to be caused by a system error that we are working on fixing currently.
This issue is being worked on by the adCenter team as top priority - No action is needed at this time
Effect/Impact on users:
Users may see high Avg CPC and spend amounts over the last 24 hours.
How long it takes to fix now will be the true litmus test.
