UPDATE: Here's the news from Sony.
"Customers outside the United States should be advised that we further discovered evidence that information from an outdated database from 2007 containing approximately 12,700 non-US customer credit or debit card numbers and expiration dates (but not credit card security codes) and about 10,700 direct debit records listing bank account numbers of certain customers in Germany, Austria, Netherlands and Spain may have also been obtained. We will be notifying each of those customers promptly."
Oh dear. The sites for Everquest 2, Planetside, and a bunch of other games are now all defaulting to a "maintenance" screen. The message reads: "We have had to take the SOE service down temporarily. 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)."
This is probably just Sony being thorough after last weeks debacle, but it's nevertheless going to be causing a few frustrations this evening.
