Hi John, on the page it says "We do note that when it comes to placement policies, it is important to keep in mind possible randomness in the physical distance between instances and the correlated effects on network latency." So are any of the placement group / placement policies features used in the test? e.g. AWS Placement Group, GCP Placement Policies? Thanks!
