Sustained IPv6 TCP Routing Degradation at Houston Core Node (bisbee)

I am a resident of Galveston, TX, experiencing severe, intermittent network outages regarding outbound IPv6 TCP traffic.

Extensive diagnostic testing confirms my local gateway is operating at 0% loss. The service degradation is occurring exclusively when traffic is routed through a specific core Comcast routing node in Houston, TX.

Technical Details:

• Failing Node: be-324-arsc1.bisbee.tx.houston.comcast.net (2001:558:2c0:2b8::1)

• Destination Records: * everybittexas.com: 2606:4700:20::681a:28a

  • www.everybittexas.com: 2606:4700:20::ac43:4598

• Protocol: TCP (Port 443) over IPv6

• Failure Signature: Sustained, multi-minute periods of >35% packet loss originating at the bisbee node, persisting through to the target destination range.

Control Testing / Verification: Simultaneous control traces to external IPv6 networks (e.g., Google) routed via alternative regional infrastructure (bearcreek nodes) show 0% loss, while traffic forced through the bisbee node simultaneously experiences severe degradation. This confirms a systemic routing/hardware failure at the bisbee node.

Action Requested: Escalate this to the Houston Network Engineering team to investigate the be-324-arsc1.bisbee node for hardware degradation or link saturation causing this routing degradation.
