I am trying to find out the same thing - how do I report a routing issue within the Microsoft network - I am seeing load balancing between two nodes that are in different continents:
8 104.44.237.42 34 msec 34 msec 41 msec ae30-0.icr02.sg3.ntwk.msn.net
9 104.44.19.137 160 msec be-12-0.ibr01.per01.ntwk.msn.net
***104.44.20.3 251 msec 244 msec be-102-0.ibr01.sg3.ntwk.msn.net***
10 104.44.19.141 235 msec 235 msec 235 msec be-13-0.ibr02.per01.ntwk.msn.net
This traffic is going from Asia to Australia in the above trace route sample - hop 8 is the first MSFT node in the path from the transit ISP (PCCW) and correctly it goes to a Singapore node, however the next hop the first packet get a response from the Perth node (which would be correct), however there is then a response from a seemingly loadbalancing node which is in Singapore and the latency is averaging 245ms.
Given this traffic is Teams Video Conferencing traffic, this is having a severe impact on performance.
So where is this raised?
thanks
