As global server hasn't commented anything about this, we can't even tell if our issue is the same as the JP issue.
Well, assuming they were the same, what they announced on JP is a rather simple notice (http://pso2.jp/players/news/26823/).
According to this, they found some problems on Personal Shop feature and other features, they decided to temporary suspend the following features,
- Personal Shop
- Item Trading
- Item transferring furnishings like Photon Capsule Machine
They will announce on a later day when these features can be resumed.
So at the fastest, the fix will happen on some later time on October 1st in Japanese time. I suppose we'd better expect for a longer wait.
