The operating system for our current server is being EOL'd, so we're moving to a new server running AlmaLinux 8.4.
Everything's been moved over to the new server, it's ready to go, but it takes a while for the website's new IP address to propagate across the Internet. Some of you will be using the new server before the end of the day, for others it will take longer, potentially a few days. The changeover will be transparent. You won't notice a thing.
I should have mentioned there are no SSL/TLS certificates yet. The certificates have to be issued under the domain name, not the IP, and the nameserver update hasn't propagated to the server yet. I'll issue them as soon as I can, but we're going to be away this weekend and my time will be limited.
The registrar for our domain experienced a hiccup. The new IP is now propagating around the world (only four days after I originally made the change) and everyone should be seeing it soon. You will likely get a security warning until I install the SSL/TLS certificates, which I'm doing now.
