Comparing the Network Performance of AWS, Azure and GCP [pdf]

An individual service effectively has infinite bandwidth relative to the available bandwidth of any of the major providers.
Not that seeing test results for service-level capabilities would not be interesting, but it isn't really a test of the network itself.
Surprised to see Azure having straightest routes and one of the lowest latencies - they always seemed to be an csp underdog to me.
Would also be nice to see some stats for traffic within the same AZ as well. I generally see ping times between 0.1 and 0.2 ms within the same AZ on AWS, would be nice to know what that looks like on Azure and GCP.
