According to official PS3 blog, Sony confessed that an external intrusion was the reason because of which the company took down the network and Sony’s Oriocity service. Further on it was mentioned that this has been done in order to verify the smooth and secure operation of our network services going forward. Sony did warn earlier that the downtime could continue for more days. However, gamers were not given a time-line within which they would resume online game playing. It seems that a hacker broke into the network and now its taking Sony time to clean up all the mess and restore everything.
