I tried to mentally follow your setup but didn't quite get it. It would seem that you've just dedicated one VPS to be the database server; did I get that right?.. If so, can you give us the specs of that VPS.
Overall, it would be nice to document in more technical details the whole setup (may be as a tutorial instead of a follow-up post?), detailing what's hosted on each vps, the specs of each one of them, the ping between the two, the traceroute path (which should contain 1 hop to the datacenter router) etc...
That's precisely what I did: one vps serving database, and the other everything else.
I've heard of traceroute, but never needed to use it; though I think I have a general understanding of it's purpose. I'd be curious to know what exactly you're looking for in traceroute.

*Racknerd advertised these as having NVME disk and ECC DDR4 RAM. I don't know how to verify that from terminal, but given the performance I don't doubt it.

I have a general mockup of the steps taken, but for a tutorial I'd want to have c&p commands and maybe some screenshots, links to docs pertaining to the tutorial, etc, which will take some additional time.
