Sony Online Entertainment has temporarily shut down Station.com, its online gaming service, following new concerns raised by the PlayStation Network security breach.
An update on the site reads, "In the course of our investigation into the intrusion into our systems we have discovered an issue that warrants enough concern for us to take the service down effective immediately. We will provide an update later today (Monday)."
SOE titles affected by the downtime across both PC and PlayStation 3 include DC Universe Online, FreeRealms and EverQuest II.
Last week SOE moved to assure its users that the PSN security breach had little effect on its services.
"We have been conducting a thorough investigation and, to the best of our knowledge, no customer personal information got out to any unauthorised person or persons," said SOE director of community relations Linda Carlson.
"We are continuing that investigation and monitoring the situation carefully; should the situation change, we will of course promptly notify you."
Yesterday Sony announced a series of "welcome back" offers for PlayStation users in the wake of the massive PSN hack that has compromised users' personal details and kept the service offline for more than a week.
