I have a VPS with Strato for almost 4 years now, never had major issues, other then broken equipment. If something was broken it was fixed asap never had an outage that lasted more then 4 hours. Good communication when they’re going to do maintenance they announce one week before or if emergency then 24 hours. The only drawback is contact for a big company they can not be contacted 24/7 but only business hours. For most sites that would be a dealbreaker.
