I don't know about their connection to TWT, but Comcast has definitely been running their transits congested. The most obvious one from recent months is Tata, which appears to be massively congested for upwards of 12 hours a day in some locations. Comcast has been forcing traffic from large networks who refuse to peer with them (e.g. Abovenet, NTT, Telia, XO, etc) to route via their congested Tata transit for a few months now, their Level3 transit is actually one of the last uncongested providers that they have.
Actually AboveNet seems to peer with Comcast: 5. xe-1-1-0.er2.iad10.above.net 0.0% 53 5.8 6.4 5.7 31.9 3.7 6. above-comcast.iad10.us.above.net 0.0% 53 6.4 6.4 6.1 6.7 0.1 7. pos-3-12-0-0-cr01.ashburn.va.ibone.comcast.net 0.0% 53 6.3 6.4 6.2 6.6 0.1 But Cablevision in New York is in fact another example of this problem: 4. dstswr1-ge3-12.rh.nyk4ny.cv.net 0.0% 78 17.8 41.2 15.0 242.9 33.5 5. 64.15.5.142 0.0% 78 44.6 42.9 23.9 82.5 9.0 6. ??? 7. ??? 8. pos-3-12-0-0-cr01.ashburn.va.ibone.comcast.net 2.6% 78 267.2 500.6 44.6 703.6 182.9 9. 68.86.91.166 2.6% 78 273.9 500.0 46.5 701.9 183.9 Peter Nowak
