They have mostly older PCs (with CRTs) and the forums are reminiscent of the internet back in the Netscape 4 days. But from what I saw it is very much an intranet that even had a dating forum. But really it is just a toy for the sons/daughters of the elite. See they very much know about the outside world and so this helps them feel like they aren't missing out on something.
Apparently though Indian workers who have been brought in to work on government construction projects e.g. the pyramid hotel can access the 'proper' internet. But I believe the governments sets up a custom WiFi network.
Also since there were no mobile phone towers around I suspect they may have an underground fibre optic network with lots of microcells around.
