The vault as we know it is dead, DNS was shut down.
However
http://neverwintervault.org is alive and well, and we HAVE everything on the old vault on our hard drives ( been preserving it for when this day happens )
However I Could use some help processing the vault data - hop onto nwn2cr or friend / message me if you want to help. I have automated tools that can process the thousands of projects, but need a lot of processing power and bandwidth ( ie bodies willing to run my application ).
( we have the files all archived, but we need to get them migrated to the API I've built before they are usable by the community again, the module listing in Never Launcher is an example of this API, so this is not just preserving, this actually migrates to the new system )
If you can host a Vault Storage API server, and happen to have a lot of bandwidth, I can get you a rsync of the complete vault which will be usable with the vault API itself. I already have many features of downloader accelerators and if I can get multiple mirrors, i can actually download one file from 5 servers at the same time, lowering both bandwidth to any one server, and also speeding it up for end users.
I am thinking the small files will use this system, and the very massive files which are popular we will try to find places to download from which do not have limits ( file sharing for example or hosted by the projects themselves ) My system will provide fail over support, everything is in the Vault Storage API, and coordinating where you download from and ensuring we never get dead links.
Regardless the usage of checksums ensures all files are exactly what was provided by the authors.
