So, it seems that youtube's ip block has been hijacked by a more

For people that don't know. The router will try to get the most specific

You are making the assumption of malice when the more likely cause is 
one of accident on the part of probably stressed NOC staff at 17557.

They probably have that /24 going to a gateway walled garden box which 
replies with a site saying 'we have banned this', and that /24 route is 
leaking outside of their AS via PCCW due to dodgy filters/communities.


I guess you guys missed the news that Pakistan has "blocked" YouTube
due to [mumble]:
