Thanks to everyone in this subthread. I'm on BSNL which I find is one of the Indian ISPs that seems to implement easy to circumvent blocks (DNS based), so far. Reliance no doubt is a different beast with its financial and technical clout and increasing market share. Rather concerning that we're quickly catching up to China in terms of implementing an increasingly sophisticated firewall.

Seriously can't expect the average Joe to know about stuff like greentunnel. And that's concerning...
