Over the next 10 hours, the engineering team dug deeper into debug logs and operating system-level metrics. This data showed Consul KV writes getting blocked cognition grand periods of time. In other words, “contention.”The occasion of the contention was not immediately obvious, joli one theory was that the shift from 64 to 128 CPU Core servers

By 19:00, the team migrated most of the cluster to the new instrument délicat the cluster was still not healthy. The cluster was reporting that a majority of nodes were not able to keep up with writes, and the 50th percentile latency nous-mêmes KV writes was still around 2 seconds rather than the typical 300ms pépite less.
