Route issues with Comcast Cbone in Marietta GA

I have several sites with Comcast Business in Metro Atlanta (GA) with issues accessing a few sites/IP.

We know the IP'S are live and not blocking since it was working up to Monday when we start noticing the timeouts and disconnects, even with Google Public DNS 8.8.8.8 the issue exists.

 

Every site using the specific CBONE stops responding and the issue is very intermittent.

 

Here is the last traceroute from one of my sites.

We can access these IP's by switching to our WAN2 with Centurylink or BigLeaf SDWAN but with Comcast seems to be stopping at be-11486-pe03.56marietta.ga.ibone.comcast.net [6
8.86.85.254]
