This site is hosted on $12/month Digital Ocean droplet with 1 CPU, 2 GB of RAM, and 50 GB SSD storage. That should be increased to 2 CPUs, 4 GB or RAM of plenty more storage for around $32/month depending on the exact configuration. There are other potential providers as well.
To be clear - I am not volunteering to host the site long term or even to help maintain the site. I am volunteering to help with the process but long term hosting and maintenance would need to come from the Sage community.
