I have received confirmation from one of ArcaneMS’s interns that the Intrinsic Network is indeed, down for good.
After a long time, Nexon discovered who the owners were, had their particulars and their addresses. It is likely that they were shut down for operating a server that is up-to-date to GMS, and they’ve also introduced jobs before GMS’s official launch (which attracted Nexon America’s attention of sending a lawsuit).
They were one of the most professional MapleStory servers that were up-to-date with GMS with incredible features and excellently coded. It was loved by many of its players. This is indeed a great loss to the private-server community.
CrypticSEA, also a part of the Intrinsic Network alliance has been shut down along with ArcaneMS.
