Cloudflare

Die kostenlose Testversion ist das beste.

Zum Beispiel, dass der Namensserver plötzlich falsch war und meine Rankings in der Google Suche komplett gefallen sind. So etwas geht gar nicht. Dafür gibt es keine Entschuldigung. Der Schaden ist enorm.

I can only say positive things about Cloudflare: it is fast, very easy to set up, never gives problems, it helps you even when the site temporarily goes out of service, you do not need assistance because you already know that you will not have big problems. All this is free (unless you need some specific options that you will pay dearly)

I would have only two details to say:
When you add the site in Cloudflare, he goes to scan all the possible subdomains and, if he receives the famous answer 200 (so that the page, and consequently the subdomain, exists) he will automatically add it. What does it mean? Some hosting always give a positive answer, even if the subdomain doesn't exist. In this case CF will create hundreds of non-existent DNS records to be deleted one by one (because it does not provide for bulk deletion)
Second thing is that unfortunately it does not plan to have dedicated IPs, even in the high paying plans.

The overall experience with them has been great. It’s not only simple to setup, but also they have a huge documentation library where you can get a lot of information: from them, compatibility with other softwares, best configurations, etc.

The results you get by just getting their free plan are more than enough for small-medium companies. Also, they hace more than 150 servers around the world, so the performance results are really great, even comparing with some other paid services.

Nothing to add here. My overall experience was really good. I never had an issue or had to get in touch with support. When ever I had a doubt, I was able to solve them just by checking their documentation library.
