European presences of US providers are still US providers with all the implications of that for privacy, applicability of US laws, government interference and a potential trade war.
Because if the actual services they used were not going through cloudflare then it would not really matter to users.
It turns out their management web UI (for orders etc.) also goes through cloudflare so that is a potential problem (and I now plan to switch away from Upcloud for that reason - its silly to route that through Cloudflare).
That said, their servers and their managent are in Europe.
