Why DNS failures, expired certificates, label selector mismatches, and network policy blocks cause more outages than packet loss — and how to debug them.
Why partial failures and latency cause more production incidents than crashes — cascading slowdowns, retry storms, and exhausted thread pools.
64% of outages come from config and change errors, not dead disks. Learn the semantic/physical failure split and why you can simulate most of them locally.
A failure catalog enumerates the failure modes that actually take down production — control plane, dependencies, config, observability — so you can test each one.
