Agreed, the uplink absolutely should have implemented prefix filtering.
However, if the Youtube prefixes had been protected with RPKI, ISPs far
away could have verified the announcements themselves - and would have
found that the Pakistan Telecom originated prefixes were invalid (and
would presumably have found the original Youtube prefixes to be valid).
As least that's how I understand RPKI.
I want *both* prefix filtering and a system like RPKI.
