Proton says it has servers in 112 countries. In reality, this number is ~40

I think only Secure Core servers are Proton’s own servers. Rest are virtuals or rented ones.

Proton VPN operates 113 Secure Core servers in 65 countries, which are available to Plus plan users.

Can’t say anything about Windscribe’s servers because I know many of the IPs don’t belong to the countries that it is showing. Yes, whatismyip is showing IP belongs to that country, like Turkey, but services which are checking the IPs are saying otherwise, e.g. Google, PSN, Disney, etc.
