NOC Network issue. Unable to connect to specific IP from Xfinity cable modems in two MA regions. Works fine from other networks.

As of this morning I have lost connectivity to our office that has Verizon FIOS.  I am in [Town removed once fixed].  Another Employee with Xfinity in [Town removed once fixed] is having the same issue.

The internet is working fine.  I have verified that my modem also is unable to ping the address so it isn't a router issue.
I can connect to the addresses from Verizon wireless and from the ISP at our datacenter.

I have been transferred 6 times when calling comcast and told that I have a customer provided modem and since the signal is fine they will do nothing else.

Is there no one who is able to get a network issue to the NOC?
