[AusNOG] Vocus routing ove Megaport IX

[Paul Holmanskikh]

Hi,

Is anyone getting traffic back from Vocus on Megaport IX Sydney ? It 
seems we are not getting anything from Vocus via Megaport IX.
There are two IPs one in our network other in Vocus with lots of traffic 
between them.  Our outbound happily flow over Megaport IX, but return 
goes around via Telstra and SuperLoop.

Is any one observing similar behaviour.  Vocus probably have reason to 
route it like that, but it is really strange.
I tried to contact Vocus NOC, but never get any response back.
