A Windscribe user shared this post
Reddit - The heart of the internet
They shared their opinion that IPinfo thinks the IP address is in Romania, but Duckduckgo (who is not our customer) and a legacy IP geolocation provider think the IP address is in the USA.
The user was helpful, supporting us in investigating the matter. It is a bit sad that they opined that the legacy IP geolocation provider is a gold standard, while they are just merely in the top position due to their legacy status.
But I respect the user for supporting my research:
135.136.1.x
Let’s review. First, let’s find a pingable IP address from the range so that we can take measurements.
$ nmap -sn -T5 --min-rate 10000 --max-retries 1 135.136.1.0/24 -oG - | awk '/Up$/{print $2}'

Picking:
135.136.1.2
For the user, we demonstrate our evidence for it clearly: 135.136.1.2 | Bucharest, AS9009, & VPN Detected - IPinfo.io
But for the sake of clarity, let’s review the evidence.
I am SSHed into one of our Romanian ProbeNet servers.
Let’s ping the IP address from our Romanian server.
root@probenet-bucharest#3:~# ping 135.136.1.2
PING 135.136.1.2 (135.136.1.2) 56(84) bytes of data.

--- 135.136.1.2 ping statistics ---
4 packets transmitted, 4 received, 0% packet loss, time 3082ms
rtt min/avg/max/mdev = 0.294/0.328/0.383/0.036 ms
Please note that we are registering sub-0.5 MS ping RTT to the IP address in question. Meaning that we can reliably geolocate the IP address in the exact data center.
We think the IP address, and thus the VPN server, is housed in an NXData data center in Bucharest, Romania.
The legacy IP geolocation service, which the user identifies as the gold standard, cannot even correctly identify the continent.
