It would help a lot if you can state what information so it can be updated :D

The wiki is updated by community as well as staff. As the latter group is often trapped within reports and tickets, there are special roles in the community called Wiki Contributor that allow the every day player to contribute and update the official wiki. This of course means it's update is tied to the players availability too.
You can apply to it if you want through the Wiki Contributor Application (https://ccnetmc.com/wikiapp/).
