Update: Made a check with their own proxy checking software some minutes again. From 50 ports were 41!!! offline. I ordered a German IPs only proxy package but in the screenshot you can see that there is just 1!!! IP from the working ones from Germany, the rest is i.a. from Thailand, Vietnam, Romania, Kenya and so on.
I hope for RSocks that their other packages are working better. If they don't want to damage their reputation further they should take all the concerned proxy packages offline immediately, refund the customers and give them a fair compensation after they have fixed their technical problems!
