The Traveler is making the required hardware/server updates so that this offline issue never happens again. If it does, you can be sure it will be temporary. The Nexus has a backup in different safe locations around the world, so even if something (god forbid) should happen to The Traveler or the server, the information is safely stored and will be put back up.
Also we are also working on hosting a mirror of the wiki in a different server. In any case when the website was down, Snozz kindly made a backup file of a lot of the wiki information, you can find his post in the shroomery here:
