[AusNOG] Telstra routing issues?

[Rob Pearce]

Hi,

Just wondering if anyone else is experiencing problems accessing Telstra networks?  Specifically the hosts 144.140.108.23 (www.telstra.com) and 144.140.200.3 (exhi.gtm.idc.telstra.com).  It's working okay from some of our netblocks, but not others.


Traffic from 103.1.192.15 works, as does traffic from an overseas host.  Traceroutes in this case stop at 203.50.79.79:

xxx at xxx> traceroute www.telstra.com routing-instance xxx source 103.1.192.15
traceroute to www.telstra.com (144.140.108.23) from 103.1.192.15, 30 hops max, 40 byte packets

But traffic sourced from 202.9.95.108 gets no reply, and traceroute ends one hop earlier:

xxx at xxx> traceroute www.telstra.com routing-instance xxx source 202.9.95.108
traceroute to www.telstra.com (144.140.108.23) from 202.9.95.108, 30 hops max, 40 byte packets
