This is some simple testing to verify that traffic from an arbitrary host in
each of our GCP regions (guc3 for us-central1, gae2 for asia-east1, g ew1 for
europe-west1) to a pod in a Shared VPC GKE cluster (in project
roughly equal latency and bandwidth.
Back in our experimental days with the
operation-covfefe-1 project, because
of the way [the network was set up][covfefe-setup], we ended up running most of
the early adopter services only in europe-west1 because traffic from other
region to a GKE pod in the same region had high latency (because of needing to
travel from one region to another and back).
