We are in the same case. Our servers are in the US hosted by gcloud, from what I could find, until the end of the year at least, it is not mandatory to have your servers in EU as long as there are some additional securities (source : https://ec.europa.eu/info/law/law-topic/data-protection/international-dimension-data-protection/standard-contractual-clauses-scc_en https://ec.europa.eu/info/law/law-topic/data-protection/inte...) But our client keep asking for the servers to be in Europe anyway
