For Microsoft Azure ExpressRoute private connections, AARNet does not charge for traffic. Microsoft will charge customers directly for data egress.
Internet connectivity to Microsoft
For AARNet members and subscription-based customers, internet connectivity to Australian Microsoft cloud services is through our domestic peering arrangements, so traffic is un-metered.
Microsoft may still charge for data egress, but may waive fees for qualified researchers and academic customers.
Microsoft pricing is ultimately a matter between the customer and Microsoft directly. AARNet is not an intermediary.
