It's something more like a water balloon fight. They're costing their targets some money and time, but not really all that much. This may escalate though. There doesn't seem to be anything permanently damaging going on though. This is a dangerous situation in many respect in that an awful lot of people think that they can act with impunity in part because there's been so little response on the part of the US or other countries. I expect this to stick with fairly tame activity for the most part. The attackers intentionally are not trying to do permanent damage for the little that it's worth. This also points out the potential use of cutting off individual countries from the services until attacks diminish from the countries. If other people can't use the service because of what's going on locally, well they won't be happy.
