We’re (AS133075) also seeing large increases in traffic today which are predominantly Microsoft related.  Some is entering our network via our Microsoft peering in Sydney but a lot is coming out of Akamai/Microsoft caches within Vocus’s network so we’re seeing it as International IP transit which is a bit ouch!

Subject: [nznog] Large increase in traffic




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?
