It could also be due to their older PPPoE setups still being a work in progress.
Yea like me 2005 from ASDL and PPPoE on BPON. ATM? = Ancient. No I must be BPON without ATM, and perhaps at first PON was ATM 15/5.
And two years goes by with no progress; congrats Verizon! I'm sure this is Netflix's fault too.
