Indeed they do but if you look at the product range they offer its still in the "we help you run your server" territory, not in the "this is a service that eliminates Component X of your architecture". I really like the Hetzner cloud!

Might be faster to ask this here:

ECC memory on the Cloud products? I'd like to assume they're using AMD's CPUs (consumer grade ECC support; as everyone should), ECC RAM, and at least mirrored storage. However I'd really like to see such basic features confirmed.

After many years of using Hetzner dedicated servers, I recently started using their US cloud for a project. So far, extremely happy, and it's very cost effective. Even cheaper than Digital Ocean (which I also use extensively).
