I have my business website on a VPS from a hosting company. A few weeks ago the website stopped working. I am pretty sure it was their fault, as I could log into the server via ssh and find ports 80 and 433 open, but they were not accessible on the web.
It got me thinking it might be sensible to have the website on another server, from another company, so if there’s a major problem I can switch the DNS to point to another IP address.
Would I be right in assuming that Let’s Encrypt would not be suitable for the backup server, and it would be better to pay for an SSL certificate valid for as long as I can get? I would obviously not want to mess around with the DNS every 90 days so certbot could update a certificate.
Perhaps another option might be to have the same private key on each server. Would that allow the same certificates to be used? I could copy via scp every week, so the certificates are always up to date.
Realistically though, just paying for a DV certificate valid for 10 years might be less hassle
