Anyone else seeing issues with traffic routing from Comcast Business customers in Connecticut?
We see that ~50% of RTP flows experience 100% packet loss while the other 50% of flows result in no packet loss. The issue is certainly in the direction of traffic sent from Comcast Business Customers towards the internet but may also be in the reverse direction as well.
The MTRs below show the path *towards *the affected Comcast Business customers. Note all are hung off of Newark -> Hartford.
