Why Playstation network is down?

So this is why..

A group of hackers called Anonymous had access to sony's database (i think). Sony had to put this on maintenence and has been trying to fix this.

This group has many good hackers such as iphone hacker, George Hotz (also known as geohotz). Sony is trying to deal with this and said it'll be down by another few weeks.

So stop jailbreaking and play properly.
