These days I seem to experience Youtube issues more and more frequently when I'm at home, especially in the evenings. Sometimes, some videos just don't stream very well while others work o.k. It seems this is related to the content distribution server Youtube selects for my location or the link to it which seem to be overloaded from time to time. The proof in point is that I can get around the issue by opening a VPN tunnel to a VPN gateway located in another country. When doing that, the video that I just had problems with just plays fine after re-opening the browser and going back to the video that I had problems with just seconds before. While this work around is certainly far from ideal, I've just found another use for my VPN.
