Seriously... DNS Server attacks are stupid. It's criminal behaviour and harms people in a way that might be unfathonable. I personally don't use feedly for anything but entertainment but there are people that use the service to feed their businesses communication structures.
It is ridiculous to assume that they really thought some mostly free service would fall to the extortion.
Congrats to that team for working hard and with others systematically shut down to get up and running.
Nothing more punk rock and open net than proving you get get around their attacks.
