Thanks all so much for your inputs!
There have been some very interesting choices an I’ve learned a lot during these readings and evaluations.
After all checking and reading and reading more reviews and what not (smoking brain ) I actually went with CloudFlare for domain registrar and DNS.
My first choice would have been Google Domains, but they do not offer the service in my country so I would have to wait until they add the feature.
So I thought, who is the second fastest DNS provider … well, CloudFlare certainly comes to mind, and they also offer very cheap domain name registration, namely 8 USD (reseller prices are not even that low!).
I am not sure if there is some sort of catch I will regret later but it seems by definition the cheapest offer ever, considering it is cheaper in name registration than all (even reseller) registrars I checked and offers free, low latency DNS with it. I couldn’t find anything copying with that.
I have read only one bad thing about CloudFlare which is that sometimes they DNS is slow - however I’ll see if that is really the case.
If anyone is interested, for hosting itself I went with WebDock, they seem to be an excellent service (pay as you go, no lock in, free mail accounts for both in an out box SMPT, different full root access VPS stacks, 1GBs link and no bandwidth or user limits, starting at 1US up to whatever you need).
At first I was scared to set up my own server (well, it is still “just” a VPS) but with their support you even master console commands and suddenly (within less than 24 hours) find yourself setting up NGINX on Ubuntu… All this for (the choice I picked) 4US a month each server is really something I couldn’t find anywhere else (well, there are always better and other choices…)
So far, now comes the big waiting if any issues pop up on the secondary sites none does… and then migrate the main site
