Just make sure any workloads you place on Hetzner are treated as spot instances and outputs are immediately sent off network. The reliability of their systems and customer support is very low. Hetzner is a 5-star or 1-star company. Are you willing to risk your business on the flip of a coin? My own experience [2] was definitely a 1-star.
