Agreed, but in this case it's just a matter of BCP.  My provider takes 
a default from Telus.  If I wanted to a default from that provider (who 
is already taking a default from Telus), should best practice be such 
that the default is sourced from my provider's AS, not Telus'?

Absolutely.  In this case, I hadn't dropped my filters in yet so it 
stuck out like a sore thumb.
