Blocking Youtube.com

YouTube traffic gets distributed via multiple URLs. To effectively block the YouTube site completely the following domains should be added to the Block List of a policy.

youtube.com
youtu.be
i.ytimg.com

If your students are being filtered via chrome extension, you can also block specific categories using the categories tab on the far right:
