Comcast (DOCSIS) issues in Boston?

Anyone seeing any issues with routing into Boston? We have a DOCSIS link
that seems unroutable past 350 E Cermak in Chicago, traceroutes from two
carries here in Michigan stop there. We have a fiber (EDI/BGP) with them at
the same location and I'm not seeing any issues on that link.

The site itself can ping it's default gateway but can't get anywhere else.
