Edge Cache and CDN Platform · View 26 of 29 · 6 · Operations
Decisions
- The proof phase tests three things first: declared keys with explain against two real properties, tag purge with measured acknowledgements across two PoPs, and a PoP serving for seven days with the control plane switched off.
- Reconciliation moves from Phase 2 to the MVP (view 17). Wildcard purge stays in Phase 2 because it needs the role and rate limit to exist first.
- A second CDN path is Phase 3 and conditional. It happens only if purge semantics can be matched across both paths, because two caches with different definitions of purged are worse than one.
Exit criteria for the proof
- Zero key-defect findings on two properties under a hostile review; purge p95 under 5 s across two continents; seven days of serving with no control plane and no expired certificate; a measured per-node Gbps ceiling; and a measured monthly volume.
Risks
- If the proof measures traffic near 6 PB a month, the right next step may be to buy delivery and keep only the key contract and the purge semantics in-house. The roadmap treats that as a valid result, not a failure.
