Wikipedia says that Indonesia has an internet penetration rate of 50%. It might be reasonable to assume that a low penetration rate means that a significant amount of the internet access is happening in a work place rather than in a residential place. If a significant amount of access is happening at a work place it might also be reasonable to assume that a lot of that access is happening over a VPN.
