Attempt to reproduce the Cloudflare 2025-11-18 outage.
Cloudflare's incident report is written clearly and explicitly, so based on my own understanding, I’m going to try reproducing this outage.
Already completed:
CK cluster
Permission change triggering data doubling
Cache propagation
Unaffected proxy services
Proxy services with bot score errors
TODO:
unwrap panic during pre-allocation of cache
Full demonstration of the entire outage process
