Checklist Mature Hosting Provider

As part of an analytical study, he decided to brainstorm on the checklist of "signs of a mature host."
Something like "7 signs of health teeth."
In general, something that distinguishes a mature adequate host (a hoster that you can trust and who does not own / does not transfer excessive risks to clients and is capable of sustainable long-term development) from a one-day hoster, is the spherical Vasya Pupkin (in Russia).
