Yesterday, US and EU PlayStation Network services went down with no apparent cause being listed for the downtime. Sony’s director of corporate communications & social media Patrick Seybold confirmed today that Sony is aware of the certain network issues, and that both regions should be back to working condition within a day or so.

“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,” Seybold wrote on the official US PS Blog.

“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.”

No further details were given about the issue, however expect to have things functional by the weekend.
