Hi there,
Good catch! We do indeed have Germany servers for Stealth Proxies, but not for VPN (yet). We use a different approach for Stealth Proxies and the locations are not permanent. You can read more about it here.
We will start looking for an optimal provider for VPN servers in Germany this year. There is one we wanted to test out, but they are currently out of stock.
Great, thank you, hope to see the new location!
