It wasn't that major, and estonia was already well protected. Cyber attacks are happening every day, there's even task forces for counter-cyber, but there'sno need to be paranoid. They want to sell you fear, make you paranoid, so they can have more power and control. This cyber attacks only affect "THEM", there's a possibility of attack on public networks but they're normally pretty simple and pretty secure, what they want to protect is banks, big companies, petrol and stock exchange markets from cyber attacks.
My bottom line is, don't worry, Al Qaeda won't train people to make your toaster kill you, they have better things to do, and so does hackers from all over the world.
