I saw this up close once.

My job involves service contracts for the cloud. We get to know workloads and optimize them and learn how to troubleshoot them to reduce mitigation time.

I had a big customer go from "must have, non-negotiable" for my team to a non-renewal in weeks when a new CTO came in. Within a month, they had an outage we could have mitigated quickly and had our yearly contract pay for itself.
