Validating network issues in a Comcast AS

  I was wondering if anybody could put me in touch (perhaps they are
already listening) with a contact point for Comcast Cable Comm. As part
of some research work we are doing, we identified some issues in their
network (in particular AS33657) and would love to confirm them. I did
email the notification contact, but got some silly automatic response.

Thanks a lot!
