For the past three days, users all around the world (including me) could not log in to Playstation Network. Official Sony rep said that the network is currently undergo maintenance, and it is expected to last for “couple of days”.
Many versions came up in internet why this is happening, one source said this was due to Sony preparation for their big MMO game launch on PSN. Many others said PSN was hacked as retaliation to Sony because of their “war” to jailbreak community. In any case, Sony is screwed. Big time.
