I transferred all my websites, other than my hosted micro.blog of course, to a single Linode instance. I set up nginx, fail2ban, and certbot from a bare Debian 10 install. I set up DNS to point 5 domain names to it, and got my email MX record set up properly on the firs try. I feel pretty good about it, mostly because I didn’t have trouble with the typical things: permissions, users, groups, etc. Unfortunately, DNS propagation tripped me up on one of my domains, so SSL isn’t working right, and it is affecting my micro blog URL, too. Hopefully I can fix it in the morning.
