The upload speeds, when connected to the VPN, were very poor, with speeds dropping to 0.6 – 11% of the ISP upload speed.

For the download speeds, when connected to the VPN the download speeds dropped to between 6 – 25% of the ISPs speeds when not connected to the VPN, although out of the 16 speed tests carried out, 15 were closer to the 25%. Multiple speeds tests using VPN endpoints around the world were carried out using using the ‘best and fastest’ server closest to the VPN endpoint, and the results were interesting. These negative results align with TunnelBear’s ‘no DNS leaks’ claim on their website. Further tests were carried out using and a number of other online DNS leak testing tools, but none triggered any DNS leaks, which could indicate that the NameBench may be a false-positive.

While performing the same tests when connected to the VPN, a DNS leak was found using the Google DNS leak software NameBench. A number of DNS tests were carried out to check for DNS leaks before testing via the VPN and no DNS leaks were found.
