That URL tells me "This video is unavailable with the Education Filter 
enabled.  To view this video, the site network administrator will need 
to add it to a playlist".

Correct me if I'm wrong, but isn't that Google's old YouTube for 
Education system which they no longer support?

Our filters have both a URI categorisation database, and a content 
analysis engine.  The content analysis engine does text analysis though, 
not video analysis.  You can still get some useful categorisation out of 
the descriptions on YouTube videos though.

Google Apps integrates with YouTube restricted mode to allow school 
staff to whitelist videos that would otherwise be disallowed, so a lot 
of schools use that.  That's Google's replacement for YouTube for 
Education, which they officially stopped supporting last year, but in 
reality it has been dead for a couple of years.

In this case, my understanding was that Darren wanted to blacklist 
YouTube, but still allow the embedded youtube videos to play on his 
local page.  With one of our filters that would be easy - it requires no 
content analysis since he wants to block the whole of YouTube.  He'd 
then just create an override for the local web page telling the system 
to allow the videos that are embedded in that page.
