Help? MetaARPA member - LetsEncrypt broken on personal site

I saw the email on Friday re: LetsEncrypt certificates for personal homepages. Checking my own personal page, I see that it's b0rked right now- https://hanzo.sdf.org and http://hanzo.sdf.org take me... well, not to my home.

Are there some steps I need to go through to fix this that I'm just missing?
