+    - Script/log context: which script/step failed and the exact command you ran.

+    - Certificates (if LE): whether port 80 was reachable from the Internet and the contents of `/var/log/letsencrypt/letsencrypt.log` around the failure.
+    - Contact info: your name, site, and a callback email.
