The issue you are experiencing with USPS is just one more example of the incompetence that USPS Tracking exhibits all too often.
I shipped a package on 10/18/17 bound for Australia. I dropped it off at our local Post Office, got it scanned in, and was given the acceptance receipt. Now, 11 days later, the tracking on the USPS site shows only the acceptance scan followed by 3 consecutive "updates" -- one day apart from 10/19 thru 10/21. All 3 indicate only "In transit to destination" with the same time stamp of 9:08am and no location indicated. There have been no further updates or scans since 10/21/17.
I'm beginning to think that the item, very well packed in a heavy-duty double-wall corrugated box and sealed with multiple layers of 3M packing tape well-burnished down to prevent peeling, was either damaged so severely that it cannot be forwarded to its destination (i.e., processed by the USPS PDU -- a secret internal department at USPS called the Package Destruction Unit) or it was processed by the USPS PTU (Package Theft Unit) -- i.e., stolen by a postal worker.
The package was 26"x13"x8" and weighed about 8 pounds -- too large to simply vanish in a puff of blue smoke, or to disappear into the nearest mirror by magic or paranormal event. Maybe a UFO came down at the sorting facility and beamed it up for consumption by aliens who like to consume cardboard to get their daily fiber requirement...
USPS should change their name to USPDA -- US Package Disappearance Agency. After all, they seem especially good at this and are getting better and better at it every day!
