This indicates an attempt to access YouTube.
YouTube is a popular free video sharing website that allows users to upload, view, and share video clips. Videos can be rated, and the average rating and the number of times a video has been watched are both published. It uses various technologies like WebM, H.264/MPEG-4 AVC and Adobe Flash to display the videos. Videos can be uploaded by individuals and also media corps that have a partnership with YouTube. If a user is not logged in with the Google Account, he/she is only allowed to watch but not comment, or add videos.
Note: To whitelist YouTube, it is recommended to have Google.Ads set to Allow/Monitor. If that is not possible, there will be a short delay before the video loads.
