Nazi Zombies, you are free to roam the earth for a little while longer as Sony’s PlayStation Network has been out of service since 4/20.

The PlayStation Network is Sony’s equivalent to Xbox LIVE, which allows for PlayStation 3 users to download games, download or stream movies and music, and have access to other services. More importantly, the network serves as the infrastructure for people to connect and play each other in multiplayer games such as Call of Duty. Oddly enough, the network failure happened to coincide with the release of several brand new games including Mortal Kombat, Portal 2, SOCOM 4, and inFAMOUS 2’s beta release. While access to the network is free, content such as Netflix must be paid for by users, leaving them wondering whether they will be reimbursed if the outage lasts any longer.

A little over a year ago, Sony users of the non-slim PS3 had a similar outage on their PlayStation Network that was “caused by a bug in the clock functionality incorporated in the system.” Patrick Seybold, the Senior Director of Corporate Communications & Social Media, posted a message yesterday on Sony’s PlayStation Blog that said, “While we are investigating the cause of the Network outage, we wanted to alert you that it may be a full day or two before we’re able to get the service completely back up and running. Thank you very much for your patience while we work to resolve this matter. Please stay tuned to this space for more details, and we’ll update you again as soon as we can.”

While there are an estimated 70 million users on the network worldwide, Sony is unable to clarify how many people are currently affected by the outage. However, players from all over the world have taken their Zombie rage to popular social media sites like Twitter and Facebook to express their displeasure with Sony.

– Update 4/23 –

Patrick Seybold has made another post on the PlayStation Blog regarding the ongoing issue:

“An external intrusion on our system has affected our PlayStation Network and Qriocity services. In order to conduct a thorough investigation and to verify the smooth and secure operation of our network services going forward, we turned off PlayStation Network & Qriocity services on the evening of Wednesday, April 20th. Providing quality entertainment services to our customers and partners is our utmost priority. We are doing all we can to resolve this situation quickly, and we once again thank you for your patience. We will continue to update you promptly as we have additional information to share.”
