The article is literally about an issue that was experienced while operating kkbernetes clusters.

FTA:

> Essentially, applications running on our Kubernetes clusters would observe seemingly random latency of up to and over 100ms on connections, which would cause downstream timeouts or retries.

Sounds like a problem affecting Kubernetes to me, and an important one.

More importantly, it sounds like a non-trivial problem that others operating Kubernetes clusters would be interested in learning how to identify and how to search for the root cause.

It has literally nothing to do with K8s. An equally suitable title would have been "Debugging network stalls on the Intel Xeon processor" or "Debugging network stalls on planet Earth".
