Postmortems
- Body parsing change for a React Server Components fix causes 25-minute outage
Urgent security mitigations still need a staged rollout; speed of response is exactly when a global config push is most dangerous.
- Oversized Bot Management feature file breaks the core proxy
Treat internally generated config files like user input: validate size and shape before they propagate, and keep global kill switches for each feature.
- 1.1.1.1 public DNS resolver unreachable for 62 minutes
Latent config errors can sit for weeks; progressive deployment and legacy-system cleanup matter as much as the change that finally triggers them.
- Workers KV storage failure cascades to Access, WARP and more
A shared internal primitive is a single point of failure for everything built on it; know which products have a hard dependency and give them a fallback.
- R2 object storage disabled during a phishing report remediation
Abuse tooling needs the same guardrails as production changes: scope checks and a second pair of eyes before an action can disable a whole service.
- WAF regular expression exhausts CPU worldwide for 27 minutes
Rules and regexes are code; stage them, and use an engine with guaranteed linear time for untrusted input.
