More bad news from Sony towers - the PlayStation Network isn't yet back online, and not likely to be so this week.

Last week Sony bods said that they should have the online gaming platform back up and running within a week but now Nick Caplin, head of communications for SCEE, has had to back down from that estimate.

"When we held the press conference in Japan last week, based on what we knew, we expected to have the services online within a week," he said.

"We were unaware of the extent of the attack on Sony Online Entertainment servers, and we are taking this opportunity to conduct further testing of the incredibly complex system.

"We know many of you are wanting to play games online, chat with your friends and enjoy all of the services PlayStation Network and Qriocity services have to offer, and trust me when I say we’re doing everything we can to make it happen.

"We will update you with more information as soon as we have it. We apologize for the delay and inconvenience of this network outage."

Before the comeback date touted last week, Sony had originally said that it would get the PSN back online the week starting 1 May.

It's not surprising then that Caplin decided against making an estimate this time.

Update: Bloomberg is reporting that the planned live date is 31 May.
