[AusNOG] For those who doubted that the communications industry is changing...

[John Gavrilita]

James,
Well, as usual, “it depends” :)
If the traffic is taking symmetric paths, then it’s ok.
If it’s asymmetric, and you’re downloading from the cloud, and the traffic takes a transit connection path instead of peering path, then you’re filling up your transit which is more expensive. But the trace you see is taking the “honest” peering path, hence the confusion.

Regards,
John.

I'm pretty confused as to why that would matter?

Hi Rob,
This actually shows the path your packets are taking on their way “there”, not their way back, which may be surprisingly different.

Regards,
John.

Congrats to Bevan and the Megaport team - I'm genuinely happy as an end-user of this service to see this path in use.
