  • Thanks for your reply but with the VPN on the speed is around 100 to 150. Turn the VPN off and it is always over 500. Even using the two closest VPN sites makes no difference.

  • Hello,

    Just a quick update on this matter, it seems that the Support Teams received a couple of similar reports as well. Based on the information gathered so far, users have experienced internet speed degradation with the VPN enabled on various servers. The development teams are looking into this and we should expect a resolution soon.

    Thank you for your understanding.

  • Seems this problem is back. Even if I used the VPN server in my own country the internet speed still throttles down to about a 10th of my normal speed.
