Based on the image they tweeted, I don't think they are doing much
filtering; the Syrian prefix was spread to a number of countries and AS. If
you have good US connectivity the impact seems limited due to better AS
Paths winning, but for less well connected prefixes I'm assuming it's more
up in the air.

Then your FBI agent should probably go through the channels
(http://security.comcast.net/get-help/contact-comcast-security.aspx)
they have to speak to Comcast, especially if it involves a threat to
life and safety. Asking on NANOG for a Comcast contact to give you
customer information (which is what it seems like you're asking for)
probably isn't going to help and makes it look more like you're trying
to social engineer some information than trying to help someone.

Re: The Choice: IPv4 Exhaustion or Transition to IPv6

And you don't need to be pushing this to customers immediately to be  
getting ready. As discussed at NANOG37, Comcast is pushing out IPv6  
initially to manage cable modems and set-top boxes (http:// 
www.nanog.org/mtg-0606/durand.html). While this doesn't benefit  
customers directly, it gets the routing environment set up to handle  
IPv6, it gets the operational staff up to speed, and lays the  
groundwork and infrastructure for when consumer IPv6 is more of a  
reality.

Considering that the only real IPv6-ready CPE at your favorite N.A. electronics store is Apple's AirPort, it seems to me that it will be several years before the majority (50% plus 1) of our respective customer bases has IPv6-ready or dual-stack equipment.  
  


Actually, out of the box my newish Linksys WRT610N started sending RAs 
and provides IPv6 connectivity via 6to4. Came as a bit of a surprise 
when it stole traffic away from my existing IPv6 tunnel. Couple of 
problems, though:


1) No switch to turn it off
2) No firewalling/filtering is done.

This makes it somewhat less than ideal, and worse than the original 
Apple Airport default configuration which at least had clear and obvious 
knobs to make it do the right thing even if they had a poor default setting.

Is that the cost for a nameplate you can stick on an empty rack with
dark glass so you can fool people visiting your datacenter? I've put
together BoMs for the CRS-1, and the pricing was at least an order of
magnitude higher.

Linecards are interesting. We get a 100Gb card, we get a linerate
14-port 10Gb card, but apparently there's still only a single port
OC-768 40Gb card.

Because when I want to know details of future major architectural
changes to a network, I usually ask a level 1 tech support guy since
he's the one most likely to know, right?

He'll know it's being rolled out when they create a script for him to
follow. One that'll likely say something like "For IPv6 problems,
immediately escalate to someone we've actually training in IPv6."
