How do I report a trace route issue on the backbone?

[bostonvex]

Hi,

Ex-network engineer here. There is a routing issue from my house in Maryland to 205.222.9.101. This is the IP address for a school website "classroom.mcpsmd.org". For some reason the traffic goes from VZ to "bad.comcast.net" and then dies after 30 hops.

Tracing route to classroom.gslb.mcpsmd.org [205.222.9.101]
over a maximum of 30 hops:

Trace complete.

After a few minutes the issue resolves itself dynamically and the goes a different route. This happens every day.

***This is the correct route***
Tracing route to classroom.gslb.mcpsmd.org [205.222.0.105]

Is there a way to report this to Advanced Networking Support or equivalent?

@dexman can you or any of your fellow Fios gurus understand what they are referring to? 

[dexman]

This issue would be best addressed by one of the Internet leads. Lucas might know how to proceed. 🙂

Oh my, you are quite the wiz! Is this for Verizon Fios or Verizon 5G Home?

Thanks for responding, this is VZ Fios. Without being able to troubleshoot it looks like a bad route is coming in through the Comcast backbone via BGP.

I've moved this topic to the Fios board for better visibility. Thank you!

Since you are an ex-Network Engineer, so I will turn up the level of discourse.

Did you confirm whether the destination prefix is advertised to AS 701 through the BGP watch glass?
