While not a small host, I thought I would mention what I observed with OVH's VPS offering. I was considering their line of VPSes recently because of how generous the cores/ram quantities were given the price. For example, the smallest offering is 4 cores / 8GB at just over $4 a month.
What I found is that it is cheap because the cores, and presumably ram, is old. Like, 2013 era Xeon E3-1275 v3 old. But that's fine! Old hardware like this uses old ram that is less affected by the current shortage. It's good enough for my needs.
Btw, Hetzner seems to have slightly cheaper offer for such small VPSs, and their disk i/o is much better than at OVH. (My own tests; I always compare the storage speed)
OVH doesn't list the eco range on their site nav now, their servers start at $90/mo unless you search OVH eco and go directly to the page.
I previously ran another VPS host who did the same exact thing (before OVH did it?).
Unlike Fourplex.net which uses modern ASRock Ryzen 9000 servers, Qeru.net used older HPE DL360 Gen9 servers.
I gave 3GB of RAM for $3-4/mo then. But these servers weren't very fast. I ended up selling the business, and am happy I did.
