[AusNOG] Netflix, AWS and Softlayer vs. Australia

[Jake Anderson]

Its true that at present congestion is going to be difficult to achieve ;->
They are also generally running a 20-25 way split (with a max of 32 or 
so as you say) so even with all users on 100mbps you would be having a 
bad time to hit the cap on 2.5gbps.

But I *presume* that given they are offering gbit services (even if none 
are available through RSP's) that nbnco would have the back end systems 
to manage congestion in the wild.
