Strange DHL Routing

Recenty I sent a document to Balikpapan, Indonesia via DHL. This is the first time I use DHL in Doha; normally I do with a postal service: EMS. With a tracking tool via its website, DHL provides up-to-date information to my document whereabout. What surprised me is the route that DHL took to deliver my document. Instead of directly sending to Indonesia, or at least to Singapore first, DHL rerouted my document to London, then to Germany. The result is the same delivery duration as EMS. I dropped my document on Monday night at DHL Office, Salwa Road and received in Balikpapan on Saturday afternoon.

Have you experienced the similar strange routing?
