What problems can arise when changing hosting?

Question

Digital certificates

I understand programming, I don’t understand networks well. I
have my own website php + jquery + mysql, there is an application for android, there are widgets for android, chrome, windows, opera, vk.
Tormented that you constantly need to sit over the server with a gun. You can not leave the server unattended for a week.
.....pffff, boiling over.
I want to switch to another hosting.
I understand that Russian servers depend on the nervous policy of Roskomnadzor, European / American - on the so far "inactive" policy of other countries.
What hosting do you recommend, and what pitfalls may arise when transferring domains, databases, files from hosting to hosting?

Answer 1

Yes, take a server from Digital Ocean , set it up and sleep well. Take a droplet in Frankfurt, it's the best for our region. If you want, I can give a referral link for a $10 bonus.
