Forget what I just said: we're moving again!
After a decade of everything working perfectly fine, and after saying I was going to leave it that way, I have decided that I want more performance out of my server.
Kimsufi had interesting offers again, so I got us a KS-LE-1 server with 32GB RAM and 4TB HDD, as well as a beefier CPU.
Everything will soon be copied over to this new server and you shouldn’t have to do anything, there will just be a complete interruption of all services on the current server while it happens and until new DNS entries propagate.
You will get a warning the next time you SSH into your account. The new server should advertise a new fingerprint for the host key, which you should put in your known_hosts file instead of the old one:
SHA256:Jag4aUwi/maRPfGRjc3PjN3uvGd0oKWvT6nY+LNK6Lw
As usual, sorry about the inconvenience. This is for the greater good, though.
