Based on the error message ("If you provide content to customers through CloudFront..."), it looks like Rogean uses AWS CloudFront as a sort of caching service for the wiki, which is a common practice.
Normally, you put a web server (like our wiki's) behind CloudFront, and then when a visitor goes to a page, CloudFront gets it from the wiki and saves a copy. The next time anyone wants that page, CloudFront gives them the copy, saving the wiki's server from being bothered.
But, in this case, it seems that copy is being used more like the Wayback Machine, in that it's being used to serve a static version of the wiki while the actual server is down. This explains why anything dynamic (not just saving changes, but even previewing them) doesn't work.
Hopefully, Rogean gets the real wiki server back up soon, but it's nice that we at least have this static version in the meantime.
