@nprofile1q... Heh I'm playing the Fedx tracking website game today as well. The website is pretty bad, and the tracking is usually a while behind the reality.
Amazon & UPS seem to track betterl, although because of GPS, radio/cell, computer & network, none of them are 100% reliable or timely.
I don't like how Fedx often won't give you a delivery time estimate until the driver is close, & won't show a map if you're not within a short delivery window. "By end of day" = no map, no clues.
