The good news is to ease your apprehension somewhat is the attack is not on the networks themselves but rather upstream at internet pinch points where traffic is directed to sights. This was done by enlisting many thousands of remotely accessible computers and overwhelming the sight by trying to access it all at once. Seems this is not just isolated to psn, as blizzard, microsoft, xbl and other gaming sights are effected in varying degrees of service delays or outage. Xbl reporting party chat and diablo3 game unaccessible but core services still running. Apparently they went after psn and blizzard entertainment first and then tried others but word got out of attacks so other network services were able to start taking measures to avoid complete disrruption. Group is claiming they part of isis and isil and is a retaliatory strike for bombings of these groups in iraq by us and nato forces.
