Whoever runs the comcast network really knows his stuff.
They are one of the first large ISPs to actually start real work on deploying IPv6.
And I remember calling during an outage and speaking to someone on the front lines (not second tier) who was actually very technically knowledgeable.
Whatever you may think of their business department (silly things like internet + cable costs less than internet by itself), the network side is really good.
I know a guy who knows the regional network manager for Comcast here in the Midwest. I hear he's actually great. Their business and management is the worst of the worst, but the poor saps who actually work on their infrastructure know what's up. It's why I was getting 10 mbit speeds back in the early 2000s.
I might be misremembering, and some of those folks may have moved on, but Comcast inherited a large portion of the '@home' cable modem network, which was, as far as I know, the first network to run out of RFC1918 space due to size and not horrible management.
You can't grow a network that large without knowing your stuff inside and out. The netops folks at comcast are fairly active in NANOG, etc. as well.
