High Latency/Congestion at Dallas ibone node (be-34932-cs03.dallas.tx.ibone.comcast.net)

Hi!

I am experiencing severe latency spikes starting at a specific Comcast core backbone router in Dallas. The connection is completely clean through Tennessee, but latency explodes from ~17ms to nearly 300ms the moment it hits the Dallas ibone node.

Because the high latency persists through all subsequent hops into the destination network, I think this is a genuine routing/link bottleneck but I also do not know for sure. I just know that when I play what I am trying to play my match gets terminated by matchmaking handler rules due to the high latency persisting. Could a forum moderator please escalate this traceroute to the Network Operations Center (NOC) or Tier 3 routing engineers to check the health/capacity of this link? Below I have provided the tests I ran after noticing this.

This is being tested with an address that I think is associated with handling peer to peer connections for the game I am trying to play that I first noticed this issue on. It is a Google Cloud address.

Approximate round trip times in milli-seconds:

For what it is worth, the loss looks ok...latency bad.
