Recently run into such unpleasant thing as copyright restrictions imposed by YouTube.
As seen in a following image it refused to show a music video I wanted to watch.
Well that's clearly unfair I thought. So, as usual, Proxy Switcher comes to rescue. I downloaded fresh batch of fresh servers,
checked along with ones I already had. Picked Elite-SSL server with a decent response time, switched to it.
Tried to refresh the youtube page but the error came up again. So I realized that I have to go back
page and then attempt to open video again. That did the trick:
Loading was longer than direct connection but that's usual with public proxy servers. Have fun.
