Is it possible that only the paperwork went to the Netherlands? Look at the times displayed. Perhaps the customs brokerage is done for all of Europe in the NL, and then once its cleared it left Korea for Poland. Still, a very well travelled system.
I can relate, having watched a system I ordered criss-cross North America several times. Eventually it went from California (on the west coast) to British Colombia (also on the west coast, but in Canada) via Chicago, Montreal, and Winnipeg.
I had another Apple part cross from the US into Canada about 30 km from where I live, but instead of turning left and and getting delivered, it turned right and travelled 3600+ km to Toronto, before coming back. I wonder how many carbon credits that trip would have needed to break even.
Hope you get your system soon!
Maybe it'll visit Venice, Athens and Damascus first. 🙂
