Persistent 0% prompt cache hits on GPT-5.5 with Auckland NZ Cloudflare 520s complicating every workaround

Yeah, this is just absurd. They are not delivering the service that I agreed to when I signed up. I was told that I’d be getting prompt cache, and they silently changed or broke that, and now I’m hemorrhaging money.

I’ve spent ten times as much diagnosing and redesigning my project architecture to work around this problem than I’ve saved with the mitigations I’ve put in place.
