That'd be me. That was a trifecta: expired CC on the auto-bill (hadn't taken it out yet), Apache was broken by a PHP update in Debian that required manual intervention in the Apache config (that did take it out), and then I needed to manually call the certbot cronjob.
Annnnnd we're back. Hat tip to Alan Burb for reaching out to me. Email is the *WORST* way to reach me. Signal, Telegram, Text, reach out to me directly if you want a more direct contact method and don't have. Jas does have SSH and Grav Admin access to the site as well as me. If there is somebody who wants to spruce the place up and keep things up to date, I'm fine with that ... but Jas has to say you're good people first. :)
