These events can be made somewhat rare within a datacenter. But they are actually very typical and very normal in communications between datacenters over the internet. Ignoring them is basically ignoring 90th percentile latency in such "geo distributed" configurations.

Which is fine, I always believed that Cockroach should focus on local clusters. But marketing it as "geo distributed" would just bring people disappointment, not necessarily a feeling you want potential customers to have.
