USPS CN # tracking

When checking a CN #, have any of you ever had this message? This is the second time I have gotten this. Last time it was delivered though that day.
Strange. I know its not a zipcode problem cause it made it to my town, and also because the last package that gave me this feedback had a correct address.

Your item was forwarded to a different address at 6:32 am on March 31, 2005 in *****, MA ****6. This was because of forwarding instructions or because the address or ZIP Code on the label was incorrect. Information, if available, is updated every evening. Please check again later.
