SEGA has posted a notice on the official site that the Phantasy Star Online 2 (JP) servers will be brought down for emergency maintenance on October 12th from 9:00am to 2:00pm (Japan time). For those of us in the US, this is going to happen around 8:00pm - 1:00am EST (5:00pm - 10:00pm PST) tonight.

The maintenance will address the following two issues:
[*]Experience after level 41 being too high[*]Ship order being reversed
