based on my experience of routing (and de-routing) my own legacy space as
well as some RIPE space through PTCL, i know they have procedures in place to
restrict what their customers can send to them, so it makes sense that they
have a clue as to how to control what they send out.

probably fat fingers, and probably fat wobbly fingers in a rush to comply with
a government directive.

"I'm Prime Minister of Canada, I live here and I'm going to take a leak."
   - Lester Pearson in 1967, during a meeting between himself and
    President Lyndon Johnson, whose Secret Service detail had taken over
    Pearson's cottage retreat.  At one point, a Johnson guard asked
    Pearson, "Who are you and where are you going?"
