Cannot access *.google.com, but other sites fine

Strange problem here, comcast phone support no help...

 

I am in Nashua, NH.  I can access most websites without difficulty.  (amazon, yahoo, comcast.net, etc).   However I cannot access any of the google sites.  This is a sudden/new problem.  Since the whole family uses gmail is really turning into a problem.   It started yesterday and is still an issue.  

 

I have power cycled everything.   I did a hard reset on my cable modem.  Went so far as to do a restore defaults on my router.   Actually tried three different routers (all working as of a couple days ago, one had been on a shelf), tried multiple computers (including a laptop that was in a bag when the trouble started), even my iPod touch is affected (so it isn't an issue with anti-virus software).   All configurations exhibit the same behavior.   I double checked the IP addresses I was getting from DNS against a friend who had access.  No issue there.   I can even see the problem when I run traceroute via my router diagnostics.  Traceroute to other sites such as yahoo work fine, here is what I get for google:

Always times out at the same point.

 

If I traceroute for yahoo I go through the same path including eighthave.ny.ibone.comcast.net, but it proceeds past there and makes it to yahoo, as you can see below:
