VZ FiOS DNS issues:

I don't care for the Actiontec boxes either, but the STB program guides and other features don't work without it, so I have mine forward all IP traffic unmolested to my own as the DMZ host (thus the dual layer of [P|N]AT you see).  It's just UDP/TCP 53 traffic that's not flowing for whatever reason; it's every device in the house phones, tablets, computers, you name it, so I'm not inclined to attribute it to malware.  My neighbor was also seeing it (and like last time, it seems to have magically resolved itself after ~1.5h).  I'm just wondering what Verizon is DOING that they are screwing up their own DNS traffic.  If they were capturing my queries and sending them to their own servers (I actually have Google's public facing servers at the top of the list handed out by DHCP) that would be one thing (irritating to be sure, but they aren't, so it's not), but when I'm explicitly hitting a name server down the street in Reston that VZ run and it's failing the same way?  It makes me wonder.
