So, some Dreamhost autocensorship bot decided to hide this. Now that it is visible, the issue has been resolved. Here is the story.
It turns out there was an unusually high load on the server. DH did not explain the cause, just that they would work on it. It was mostly resolved within 15 minutes or so.
So, if you see this, I would suggest immediately opening a support chat session, if you need it resolved quickly, as I did.
