Anybody wondering why the AISLive service is not providing so much information now to the free subscribers? Its not a system problem, they have recently limited the free public service to showing only the overview charts in all areas. They have also increased the delay to a minimum of 6 hours.
So they can force the North Koreans to pay...?! I mean, they have some old ex. Soviet submarines right? Nothing in the same class as the Typhoon hopefully (hint: Hunt For Red October) but adequate to enforce their own "if N. Korean ships won't be allowed into foreign ports, foreign shipping may disappear in the Sea of Japan unexplainedly" policy... So, they should at least have to pay commercial rates for having precise info on commercial shipping...
