We're seeing a large increase in inbound traffic levels today.

Appears to be coming in both over peering links and internationally. Right now it appears to be Microsoft related.

An AKL-IX graph shows it well - http://monitor.akl-ix.nz/cacti/graph.php?local_graph_id=14&rra_id=all

Or the MS port:��http://monitor.akl-ix.nz/cacti/graph.php?action=view&local_graph_id=137&rra_id=all

Does anyone else have more information to add as to what MS patches or similar are causing this? And over what borders this traffic is entering their networks?

Cheers

Dave
