Our current server is hosted with Rimu, so I would go with that again. I've set up an order with similar specs to before, but slightly less disk as it seems we're not using it. (We've not exceeded 23gb in last 12 months). Also saved a couple of dollars/month by going without backups (i figure we don't need it and can re-deploy in the event of disaster).

Only thing is, they don't support Ubuntu 20 anymore! Maybe if we ask nicely they would. Or maybe we can upgrade the current machine in place?

From Rimu:

One option may be to clone the old server into a new instance, and then update that using the normal distribution upgrade method? Then you can stop anywhere along the path?

They suggested trying their guide: https://rimuhosting.com/knowledgebase/linux/distros/ubuntu

An automated dist-upgrade using our 'distrorejuve' tool. There are a few steps to dist-upgrading an Ubuntu server. We have automated those in our distrorejuve script on github.

Looked at other hosting options here: https://docs.google.com/spreadsheets/d/1_Hr3UbbQdWmraaloL-bQXeHbC1ziFy9LJ8ydMDmDuSk/edit?gid=1404766143#gid=1404766143

I've de-prioritised this. There's no other great options. I'm going to proceed with upgrading other servers and see if it's realistic to install with Ubuntu 20. If not, perhaps we will need to upgrade Ansible/python etc before proceeding.
