My wild guess is: they might not have had any internet connection at all. But it really depends whether the Koryo Tours guys thought the extra cost would be worth it. I don't have any updated pricelist from Nosotek (the North Korean/Dutch joint venture outsourcing firm which wrote Pyongyang Racer), but back in 2010 they charged an extra €40 to €60 per day surcharge to clients if they wanted their team of two outsourced Pyongyang programmers to have direct internet access; otherwise the team would work "in a cleanroom environment and can not connect to the
internet" and all email contact would be with the Nosotek managers only.

To put this in perspective, that charge is almost the same as the charge for one of the programmers themselves. My guess is, Nosotek most likely have to pay for a third guy from the government to watch the browsing habits of the first two, and that third guy has to belong to both the set of political reliables and the set of internet-savvy people --- two sets which are already small in North Korea and whose intersection is even smaller. Not to mention the cost of the extra computer and internet connection itself
