Probably everyone had encountered that problem at least once or twice: you open a link to a Youtube video, and the video is blocked, or even Youtube itself does not load if you are browsing from a work/school computer. Reasons for Youtube videos being inaccessible may vary. Sometimes it’s organizations or schools blocking Youtube on their networks to save bandwidth and to prevent employees or students from slacking off. Some countries (for example, China PR, and others) restrict access to certain videos or even to the whole youtube.com site. Finally, some videos may be blocked in some countries due to copyright issues or because the person that uploaded the video set restictions for certain countries.
