Dreamhost now offers free SSL certificates via Let’s Encrypt, so I’ll be trying to make that work over the coming days. For the moment, I’ve turned it on on the wiki. It doesn’t seem to work yet; visiting the site over HTTPS returns a Dreamhost error page. I don’t know if it takes a few minutes/hours or if something went wrong. Accessing the site over unencrypted HTTP still works, though, so I’ll leave it like this for a while.
If anyone has problems because of this, alert me in the #server channel on Slack.
EDIT: Seems to be working now!
