Sony Online Entertainment, the MMO arm of Sony's empire, has taken its services offline due to an issue which has caused "concern."

Sony Online Entertainment's services, also known as, have been taken down temporarily. The official site states that "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."

This is something of an about-face from the company's announcement last week that they believed no personal information had been compromised. The intrusion into SOE's systems came at the same time as the PSN security breach, but SOE representatives believed that was separate enough from PSN for subscribers' personal information to remain safe. The only game with a direct link between the two services is the PS3 version of DC Universe Online, which uses the PSN wallet to fund subscription fees.

SOE says we can expect an update on the situation later today.
