Due to IGN's direction, the NWVault website, originally hosted on GameSpy's network, has been closed down sometime in the past week. Since GameSpy's online presence was taken over by IGN, it seems they've decided to shut down the vault in order to turn it into a mere redirect link to their wiki page on Neverwinter MMO. Because, you know, that seems like a sensible thing to do.
I've been following a topic on the
BioWare Social forums to see if anything new crops up. Thankfully, it seems that the people behind the similarly named
"The Neverwinter Vault" have been backing up the NWVault itself for some time, and are looking to upload its content once they get things working. Plus, the Nexus network still has a page up for Neverwinter Nights 1 and 2 if need be (Find that
here!) though hasn't been updated so much.
If you've got portraits, overrides, and modules you find to be essential, please start backing them up. Who knows when (and if) the content could be found again.
