"Act of God is a legal term for events outside of human control, such as sudden floods or other natural disasters, for which no one can be held responsible"
Do you think nobody can be held responsible for this breach?
Just because we can hold individual humans accountable (and should) doesn't mean we shouldn't have the perspective of "CONSTANT VIGILANCE."
Certainly should have to treat intrusions as inevitable in designing the system, but there still is responsibility on the part of the intruder.
I lock my door because I consider it inevitable that someone will eventually try and break in. However, if someone does break into and vandalize my apartment, I sure as hell would consider them responsible and not consider in an act of God.
Does it matter to you if some kid in Australia is brought up on charges? No?
Does it matter to you if a hosting company is competent in securing their servers? Yes?
Any discussion of who did the hack servers no purpose other than to distract from the only issue that matters to anyone which is PHPFog's security.
