Hi there,
We are weighing the pros and cons of each DNS. While they may have a good case privacy and location wise, OpenNIC has been less than reliable in our experience.
Then why not use Swiss/German Privacy foundation servers? When I first brought the issue up you said it was because of server downtime. I was playing around and for me the up-time seems to be at a good 99%+, If you really wanted to you could use one of each DNS servers, but really you don't need to, they have never failed on me or been down before, I think they are more then adequate, and the privacy value is much greater then with Google or OpenDNS. Its one of the reasons I asked for a "Input DNS" box in the new version of the client, so if people wanted to use their own DNS server, they can.
(Or maybe just use the Default DNS for the OpenVPN server we are connecting on, which most other VPN companies do, and BolehVPN did before changing it for some reason)
Just to give a clear explanation to why Google is a bad DNS provider for a VPN service.
(Privacy
It is stated that for the purposes of performance and security, only the querying IP address, which is deleted after 24 hours, ISP, and location information (kept permanently) are stored on the servers.[15][16][17]
According to Google's privacy policy,
"We [Google] may combine personal information from one service with information, including personal information, from other Google services". While there is no mention of the DNS service in the main policy—the privacy page of the DNS service states that information is not "correlated or combined" with "personally identifiable information"—the question remains whether a generic but persistent tracking identity is considered "personally identifiable information".[18])
In bold is the issue, using the exploit I have explained before they can correlate DNS requests to email accounts, YouTube and pretty much anywhere on the web with a Google trackers or analytic. Basically say goodbye to the privacy afforded by a VPN.
