Hi Inflatable.
In 2015 the server closed.
In September 2016, the server re-opened, but all items+zeny from before that were wiped (except Donation Credits, which were refunded as Legacy Credits).
On August 16, 2018, when the server relaunches, everything will carry over from the last time the server closed (December 12, 2017).
All accounts and characters from back then are still intact, but if you haven't logged in since before 2016, all your characters will be level 1 Novices and you account will be empty.
