When comcast access my site they have to go through this node:
100% packet loss through 152.179.220.125 n-a.GW13.NYC1.ALTER.NET
After that, they get 100% packet loss.
My business cannot run with 100% packet loss. Customers are complaining big time. FIOS tech support, I have opened a case, please fix the problem.
And this is only site I have access and can collect data. I believe all my comcast and ATT customers are having this issue.
