[AusNOG] Optus/TPG blackhole

[Tim Sandy]

Seeing some issues with Internet routing, particular subnets are
unreachable from at least TPG NBN/ADSL.

Traceroutes get as far as the Optus network and then drop. Both TPG and
Optus looking glasses are seeing my routes and can successfully ping my
network.


Interestingly too, tracing from network back to the hop where my traffic
disappears - Traverses the same previous hop and gets a response.


Trace INTO my network;

Anyone else having problems?
