[outages] Spectrum DFW routing issues

[David Eddleman]

Looks like there's a router in Dallas that's dropping certain
routes. 96.34.3.69 seems to have issues forwarding certain connections
along.

And just to prove it's not a one-network issue:

Bizarrely, portions of some of those networks are reachable.

Trace complete.

Already let Spectrum know after having to jump through some hoops, but if
anyone is experiencing similar behavior let me know and I can give you a
contact to reach out to.
