Sony has addressed the ongoing service issues with the PlayStation Network in a post to the PlayStation Blog.

"The video game industry has been experiencing high levels of traffic designed to disrupt connectivity and online gameplay," Sony said. "Multiple networks, including PSN, have been affected over the last 48 hours."

Sony said that there may be more disruptions in service due to surges in traffic, but that its engineers will continue to work to restore service as quickly as possible.

"If you received a PlayStation console over the holidays and have been unable to log onto the network, know that this problem is temporary and is not caused by your game console," Sony said. "We’ll continue to keep you posted on Twitter at @AskPlayStation and we’ll update this post once the problems subside."

PlayStation Network's status was improved to "intermittent" for a short time earlier today according to PlayStation's official website, but is now offline again, as you can see in the message above.

Sony hasn't said when network services will be back in full. Keep checking this story, which will we continue to update with new details as they come in.

The PlayStation Network is slowly coming back online for the PlayStation 4, PlayStation 3, and the PS Vita, Sony has announced late last night via its official Ask PlayStation Twitter account.

We in San Francisco were still unable to connect to the The PlayStation Store via the PlayStation consoles, but other users around the world are reporting they had more luck, and we were also able to connect to the PlayStation Store website on the PC, which wasn't working yesterday.

PlayStation Network was also still offline according to PlayStation's official website, as you can see in the message above.

Sony hasn't said when network services will be back in full. Keep checking this story, which will we continue to update with new details as they come in.

UPDATE -- 3:54 PST

Still no word on when to expect PSN services to resume, though both users and some GameSpot staff have had random luck in both getting online and connected to some games.

According to Sony, "No ETA available yet, but our Team is working to fix it as soon as possible, thank you for your patience."

UPDATE: The PlayStation support twitter account has begun issuing updates, telling individual users, "Our engineers are continuing to work hard to resolve the network issues users are experiencing. Thank you for your patience."

However, when will PSN be back online? Sony says, "No ETA available yet, but our Team is working hard to fix it as soon as possible. Thank you for your patience."

The original story appears below.

Following network outtages for the PlayStation Network that started on Christmas Eve, and which extended on Christmas day to both PSN and Xbox Live, Sony's online gaming infrastructure remains offline today.

The Xbox Live status page currently lists all core services for Xbox 360 and Xbox One as "up and running," though access to apps for MLG.tv, Maxim, and IGN are "limited."

PlayStation Network, meanwhile, is completely offline according to its status site (and verified by the fact that I can't log in online). Sony has not issued an official word yet on the cause of the attacks or when it expects online services to be operational again. We'll update this story with further details as they're made available.
